Mercedes Sprinter Camper Conversion - Roof Fans

[@GregVirgoe]

FAN UPDATE VIDEO - we have now changed these fans for Maxxfan Deluxe which are far better. To watch that video please click here kzbin.info/www/bejne/f6ile3p_q82sd8U

For me the iconic KZbin image of you is the opening still of this video with your head through the roof. Simply perfect.

Dude, we just bought a Ford Transit, and your videos are legit the only ones I trust to follow for my How To guide! Thank you for making these!

I wish you were my neighbor here in Portland Oregon in the US... I'd be bothering you to help me EVERYDAY... with everything... But especially my van build... you are so clean and clear in how you do everything... what a great teacher!

Princess Pamela's World thank you for such great feedback. Guess I would be very busy 😃👍🏼

[@RandomYTStuff]

Your attention to detail is educational. Too many people mess up the little things, which makes their work short-term and necessitates further expenses and uncomfortable corrections down the line

[@GregVirgoe]

I’m trying to cover all the steps that most just gloss over. Thanks for great feedback 👍🏼

A big thanks for that Greg, I was puzzled when I noticed big grooves on the roof!!

[@barryjameson3113]

I bought a Fan-Tastic 7350 a couple of weeks ago and haven't found the time to put it in. It's easy to get in California through Amazon. Glad I waited and saw your video. I was going to go by logic, as it is relatively easy. Then, I saw others doing all kinds of unnecessary things. I like the wood addition and will be using it. Your videos are really clear and thanx from another Brit from Scotland living in Cali ….

Thank you, Elaine, are you doing your own conversion?

[@iangadget3848]

Greg, you have the neatest fan install on KZbin that I have found. I'm installing two Maxxfans in my sprinter this week and am using your video as a guide. I plan to use plastic screw caps filled with sealant over the screws for a uniform look and to protect the sealant from Sun and UV. That is the only way I thought of to improve on your brilliant example. Thank you for the whole video series. I know there are many people around the world following your tutorials. They have been recommended to me several times, but they are preaching to the converted. I might christen my van Greg, or at least GV, Greg Virgoe and Great Van, same initials, go figure.

[@roycameron6943]

What an absolute gent'. So helpful to anyone even thinking about trying a van conversion. Much appreciated, Greg.

[@carollewis8115]

What a great video! I've been watching dozens of them where people use a whole tube of caulk on the final seal and make a huge mess. You were 1 out of about 25 installers who cared enough to do it right. Well done!

[@nomadcarpenter8549]

Cheers for the clear and easy to follow instructions, my conversion would have not been started had it not been for your video series.

[@ChristopherJamesable]

Thanks Greg! Thanks to your tutorials I had the confidence and all the right tools to put my own roof fan in my own sprinter. It poured with rain later that night and not a drop got through. Keep doing what you’re doing!

[@GregVirgoe]

That's fan-tastic news :D see what I did there lol Seriously, glad it was useful to you. Cheers

[@harveysmith100]

Nice install and nice fans. I love the blower feature so you can really get a good cross draft. Good for keeping condensation down. The silicon scrapers are excellent, I was never happy with my beads until I watched the "ultimate handyman" show a product called a Fugi kit. Worth a watch and the Fugi is top notch.

[@GregVirgoe]

Hello Harvey, I looked at those and essentially exactly the same tools. Great the way the silicone does not stick to them and perfect beads every time. Thanks for your support.

[@thecorbies]

Hi Greg. As you mentioned in the video, sooooo many people use about 14 tons of silicone and spread it with (what seems like) a dead ferret or similar. Anyway, you did an excellent job; well done. Regards Mark in the UK

[@GregVirgoe]

My other half wants to know what I'm laughing at. I thought your dead ferret comment was hilarious. Thank you for making me laugh, glad you liked it.

[@kennethskou5597]

Actually a dead ferret is A LOT easier than a live one for spreading silicone - just telling you. :-)

[@arnoldtarbooz1420]

Very nice job.. I like how you described the fan's features and why you bought them.. someday I will get a sprinter and will do some cool things perhaps with it - and take trip around the gold old USA -

Thanks Jody, I'm a bit of a perfectionist, like to do things to the best of my ability.

[@jameshanson5610]

Thanks, great help! I am nearly ready to get started on my build. I have a xlwb Sprinter. I have high standards but I am very new to this. KZbin is a god send. Keep em coming. Cheers.

[@GregVirgoe]

Wow +James Hanson, so you have the longest one? Mine is approx 4.3m long in the back so how much more room have you got? What are your plans with the interior?

[@bforseth]

Excellent video. The fan install is for sure the part I will be most nervous about when I do mine but this made me feel a lot better about it.

[@GregVirgoe]

Hi Brent, cutting a big hole in the roof of your van is very a nervous time for anyone but if I cab give you a couple of bits of advice it's these. Measure, measure and measure again. Then make sure you have a new fine toothed HSS blade and it will make the cut much cleaner. Thank you for watching and best of luck with your build.

[@GregVirgoe]

That sounds just fine, you do need ventilation for cooking, both for combustion of the gas and toe tract the condensation build up. If you have opening windows and doors that with a single roof van will work

[@velorucionLDN]

Hi! Posting the links of the products you used is great help! The install looks very clean! I need to learn how to make really straight cuts with the jigsaw, somehow mine always turn out a bit zigzaggy

[@GregVirgoe]

Hello Konstantinos, I used a new blade for each fan and they cut really easily. They were very cheap from eBay so it was the best decision to make. Thank you for watching.

[@MattyMeltzY]

You are a legend, Poppin your head through the hole had me cracking up. Currently researching future build from Washington State, cheers.

Nice neat job Greg and forward thinking on the slot in the wood for the wiring to go through. Thanks

[@GregVirgoe]

Ah, you noticed Keith, well spotted. It was a bugger on my own to feed the wire in on the first one, it was covered in sticky mastic. You can probably see I got tagged a couple of times. Not good with my hairy arms, hehe The second one I got my father in law to feed the wire from below, lesson learned.

[@keithjohnson3275]

Greg, i dont recall you saying which sprinter you bought, long wheel base high top? Many thanks

There are a lot of van conversion videos out there, but yours are the best! I will use them during my build, thank you very much good sir (:

[@GregVirgoe]

Thank you for such great feedback. Cheers

[@charlevoix418]

Sikaflex is also sold in Canada, I discovered thanks to you that there was a primer No. 210 to be used prior the application of Sikaflex sealant: I will look for it here. I am watching tons of videos about caravan construction and van conversions, either from North America and Europe and I noticed that North Americans were putting tons of caulking over flanges and screw heads, Europeans were not. I think that effective sealant should be located UNDER flanges and screw heads, not over. It is the first time I see someone from Europe putting sealant over screw heads.

[@GregVirgoe]

Anytime you are dealing with potential water leaks I’d rather be “belt and braces” which is why I did both.

[@yairlevi8568]

Greg you are the best van-convertor, i wish i had half of your skills... I can go and design a whole new microchip, but for sure i cant fit van fan

[@SethsAdventures1977]

Great videos brother! I am in California doing a Sprinter van conversion. Your attention to detail is first class! Thank you for your wonderful video’s. Cheers

[@andrewbooth7352]

Cracking tips as usual Greg. We're looking forward to doing our on conversion as we are away quite often with our daft Springer Spaniel and your tips make it look achievable by mere mortals! One thing I have discovered when cutting holes in thin materials is that it vibrates. A lot! To minimise this, after the first cut, I put a piece of gaffa tape over the cut to hold it in place, then do the other three. I find that cuts down (see what I did there?😏) on the vibration and reduces the risk of creases on the skin of the van. I hope that helps? Keep up the great work 👍

[@davidanderson5893]

Great work Greg looking forward to the next instalment. Thanks for the links to the parts needed as I was needing the sealing compound but didn't know what it was called. Thank you and keep up the good work and videos.

[@GregVirgoe]

No problem David, I put a search result up there as they do many different thicknesses and widths. I used just over half a 10m roll of 32mm wide x 2.5mm thick.

[@alixr5926]

You have GOT to be an engineer by trade. ;) That's a really solid fan installation, especially with that support frame underneath. We use Sikaflex on the boat as well (not the caravan stuff, of course). Really happy with it as a product. And yeah, one doesn't need tons of it (though on a 40 ft boat, it adds up).

[@NH-po8wr]

Nice video, super neat finish. I'll be starting my van project middle of August once I find a sprinter of my own. Been watching your build series and its a delight. Thanks for the content

Hi Greg, thanks for another great video. Is there any concern that the holes created by the self drilling screws will experience rust? Or am I just being paranoid here, and the screws are such a snug fit in the holes that this shouldn't happen?

[@GregVirgoe]

Don’t worry the screws are a very tight fit so no hole and they are surrounded by mastic sealing tape so no water will get near them. 👍🏼

[@meobridger4096]

@@GregVirgoe Ok, nice one. Thanks very much!

[@norfolkbushmanandfriends7916]

would it be a good idea to put a blob of sika flex on each hole before driving the screws home? Maybe it would help prevent any water getting in through the screw if the blob on top fails. Great video by the way, i'll be following your methods for everything on my build 👍👍👍

[@moreorlesslikeso]

Having done some campervan conversions myself I really enjoy your work and the thoughtful planning before the/any act. Your videos are definitely a joy to watch! However, I wouldn't really dare to handle that sharp edged metal while doing those cutouts with no protective gloves on my hands. The guy doing the windows (in a previous vid) also seemed to do the cutting and bending away the cut metal strips with bare hands... Don't ever do this (especially) when your experience with that kind of work is somewhat limited, I' say. You'll need both hands and preferably all fingers intact for the work to come in further stages of the conversion.

[@GregVirgoe]

You are absolutely right. It is always best to wear gloves when cutting metal. Sorry I forgot to put mine on in that video and well spotted.

[@GregVirgoe]

Since finding the Maxxfan I have never fitted anything else. There is nothing on the market that is anywhere near as good. I’ve fitted one on the budget build van. Look at the more recent video series.

[@ginsudan]

Greg you put two fans in the roof, right? It seems the first part of this video was the front and then you finished up with the rear fan mount, am I right? Do you have more video of the front fan installation? I don't plan on installing a fan in the rear unless it becomes necessary, then I will do it later. So I would like to see how "you" installed the front fan, if possible. Thank you your videos are very helpful. I especially like the way you reinforced the sheet metal with the wood frame.

Hi Greg, I love your video series, it's my first call for my van conversion. I have a question that I don't think has been asked yet. I'm installing my roof vent fan on a flat spot on my van (no ribs, though the roof is slightly curved). Would you still recommend a layer of mastik all the way round the edge of the fan, or just fit it slush to the roof? I imagine the mastik would help get a good seal?

[@GregVirgoe]

The fans are the same size. The thing that’s different is the size of the flange. You can order a 355 flange or 400 flange. Check which one you have ordered as that will give you the answer to the hole you need to cut. Come back if still stuck and I’ll try help more.

[@clasrobinson6544]

@@GregVirgoe cheers Greg I think i sorted it now, it' s because the flange that goes on the roof has a raised bit that goes in the cut hole (which won't because like the sprinter the crafter roof is not flat ) that's why I have to cut hole to 400x400mm .

[@GregVirgoe]

Thank you for such great feedback. I just checked out your BMS video as I was only yesterday looking at Valance Lithium batteries that have a BMS system you can hook up to a laptop via an RS483 to USB connection. What make are your batteries?

[@EatSleepVan]

The batteries are by Boston Power, although they are generally not available to consumers. They're also Lithium Ion, I would recommend anyone goes with Lithium Iron Phosphate (LiFeP04) instead in a van, much safer if anything goes wrong, and more commonly used. I still recommend a BMS with them. I've got another video on the batteries as well. A built in BMS in each battery makes sense, as long as the batteries are the right voltage and thus are then in parallel. Otherwise you'll need to balance the batteries too.

I'm converting a Welfare wagon, 2013 Sprinter 310 so most of the facilities are already installed, except roof ventilation, and beds. One issue is that it already has a liner and I'm concerned about if there is any insulation, and removal and replacement of the fabric liner. Finally, I was really pleased to find the front passenger seat kit you featured in another video, I had heard one was available but so far hadn't found a supply. I haven't watched all your videos but will continue to view them as you do a really good job. We went to Italy this summer in a hired camper van and now have the bug, just in time for retirement.Regards & Thanks Mike Barry

Hello Mike, are you in the uk and is it a clear one that you are after? What type of van do you have please? Cheers

[@mikebarry3879]

Yes we live in Northampton, I think that a clear lid is our preferred choice, Our van is a 2013 310 Sprinter

Excellent video, thanks a lot for sharing. I have a question though - aren't you worried about the screws you added at the end - the debree they've created while going through steel will rust, won't it? I am wondering if I should draw the holes first.

Really helpful thanks. Only question is which type of Sika - 512 is air cure by moisture in the air and will not cure if it is too deep. It seems that Sikalastomer 710 Butyl sealant might be better for the seal but not as an adhesive?

After you finished cutting the roof out then wiped it down ?? Then, when you put your head through the roof, the roof profile had changed ???

[@GregVirgoe]

I cut two holes for two fans, one front and back. Well spotted 👍🏼😊

Hiya! Following your guide now. Not sure if you know..... but how long does silkaflex take the cure. If its going to rain and I cover it with tape/plastic bag will it still cure?

[@GregVirgoe]

Bellina Fiorelli it will generally be cured by the next day. Colder weather will make the time longer.

You're an absolute gem!
