What Else Did I Find on the 2008 Marquis Suspension?

[@timk.9827]

Glad I stayed to the end of the video, Thanks James

[@CAROLUSPRIMA]

This is rapidly becoming my favorite KZbin channel. James isn’t only an RV expert; he’s an expert communicator. Further, he has that indefinable characteristic that makes him fun to watch and can neither be taught nor learned. We should revere more the “Jameses” of the world. As one with an earned doctorate I think that I can say with some authority that what James does requires at least as much brains and skill as my job and is far more useful.

[@AZExpert]

Thank you very much! That's very nice of you to say

[@SpykersB]

My first lessons on a coaches air suspension, and I’m watching very intensely….surprised myself. Because there is no way in this life time I would actually go and search the internet on this subject to learn more. You could make watching paint dry interesting! Cheers 🍻

[@AZExpert]

Great to hear!

[@Robasteerjock51]

My 08 Beaver Marquis (sister to this coach) has now had all of the ride height control valves replaced as well as the Valid controller board... the solonoids rarely go bad according to the Valid Tech line... good luck, we enjoy following your vids.. you arent afraid to tackle anything, which makes you credible.

[@JohnnyQuest1960]

Remember that fix well , Went through 3 leveling valves before we found one that worked !

[@AZExpert]

Thanks for watching!

[@patrickmclaughlin6013]

after watching a ton of AZExpert videos, I think a nice tent is a good option.

[@VitoF111]

What a beautiful coach. Wow, a 600 Cat! I love these old Beaver coaches.

[@badgerpa9]

Thanks for the ride height explanation. When I had to figure out mine on a van a few years ago it seemed like none of the mechanics at the dealership had a clue how it worked and messed it up. Once you spend some time looking at them and finding the spec sheet it really is not hard to hook it up right but you need to follow the instructions. Glad you had a nice trip.

[@frankietuned]

The answer is pretty simple and a very easy mistake to make. You actually solved it during you explanation of how the leveling valve works. The leveling valve is installed upside down. The exhaust port should always face down. Simple flip the leveling valve and it should be good to go. On a side note, I'm from Chicago and we stopped at that same exact Chevron on our way to the Petrified Forest by Holbrook.

[@AZExpert]

lol nice

[@bpnracing1256]

We used to mess with airbag systems delivering decked freightliners. Couple other ways to do it. Best option would be plumb into the good side with the leveller that worked. It would just level both sides the same. 2nd option just put a Schrader valve on a single line coming out of the airbags that were wonky and manually put air in it to get it close.

[@jamesdrew7315]

Another awesome video!!! thank you James for all the help you’ve been!!!Knowing that someone like you is out there, gives a newer RV owner like myself some peace of mind! Thanks again!

[@AZExpert]

Thank you

[@johnstanczak5075]

Agree with you that the line should not be plugged off.... should have been a MAJOR clue to who ever replaced the Ride Height leveling unit that something was not quite right, but in all fairness, it could have been a road repair too..

[@solvend]

Road trips are the best. This makes twice you've been through OKC in last few months. Keep on kicking ass!

[@ferrelx]

Happy 4th everyone..raining like a mother here in RockPort.TX thanks for reminding me brother why I love my gas motor home 😊

[@AZExpert]

I still like Diesel

[@ferrelx]

@@AZExpert Diesel defiantly has some advantages..but when I found this model 4 years ago I was smitten and would trade in my 2005 Itasca SUNCRUISER 37B for this rig..now Big Bo is kind of a blow hard but this is a pretty good representation of a 2004 Winnebago Chieftain 39T ---> kzbin.info/www/bejne/rGXIqqxpi91jbbc

c'mon back to LR & take a jab at this Class C...2000 Catalina Sport 30ft...I have most parts ready for install, but you obviously know what you are doing...heheh

[@RVingwithAndrewSteele]

What a mission! Another great video buddy!

[@AZExpert]

Thanks Andrew!

[@DavidRussell-TheDavidRussell]

Loving your channel as we are about to go full-time RV. Just notices at the 11:14 mark that you were in Morrilton, AR and you drove right by the Morrilton Drive Inn. Best burgers between Little Rock and Ft Smith. Hope you got one.

[@AZExpert]

Thanks for the info! Maybe I will be back there some time

[@ronroybal7062]

I’ve learned so much from your videos! I am curious to see a part three.. Thanks!

[@AZExpert]

Awesome, thank you!

[@richardstewart2680]

Thank you for going over the ride control valve, and how it works, please let us know what the problem was, and how you fixed it 🙏🏻🙏🏻🙏🏻🙏🏻👍👍👍👍👍😁😁😁😁😁

[@AZExpert]

It's awful

[@diesel46809]

When I run into that problem I usually just plumb into the other side ride height valve just for a quick fix. Good job though. Alot of people can't fix those

[@AZExpert]

Thanks 👍

[@PreacherwithoutaPulpit]

The whole time you were under that thing I was on pins and needles. I grew up turning wrenches in my grandfathers garage and almost managed to crush myself once. Now anytime I have to go under a vehicle it's a constant fight to remain under it until the jobs done. It doesn't matter if I know that there's no way for what I'm working on to crush me, that fear is still there...

[@AZExpert]

Its always something I think about.

[@stevesmith9173]

Staying tuned in for the next video

[@Kingjamesvii1]

If that is a Barksdale 55521 series cab valve. The two ports together go to the bag or bags. Then the inlet and exhaust ports are on opposite sides. So the spare ports together should have the extra plugged like they did. But from the angles you could get the camera at I couldn’t see the exhaust port.

[@AZExpert]

thanks for the comment

[@robalward5643]

I own sister coach to this one.. changed all the ride height valves and carry extra..the system is complex..the RH valve is bad

[@AZExpert]

Always issues

[@rnreajr9184]

It looks like you're driving a right-hand drive car - Arkansas, UK!

[@AZExpert]

Yeah the camera flips

[@rh-cv3nr]

Great video but would love a conclusion :-)

[@pault1964]

Excellent as always

[@petepeterson5337]

My GUESS is that with a correct leveling valve, the old control board will be happy. Different behaviors in a fault condition could be due to different firmware in the microcontroller. I work with embedded software engineers who are very good, but my god can they screw stuff up if there isn't good engineering at the system level.

[@VideoByPatrick]

Do you ever trek to Florida ? You could easily play Clint Eastwood. What ended up being the solution to the faulty air bag ?

[@Therberg2500]

@AZ Expert Love the channel! What was the actual solution to the suspension issues on this coach?

[@LayloNewt]

Thanks for the update. Enjoyed it

[@AZExpert]

Glad you enjoyed it

[@danthemanrvrepair6338]

Another grate video👍

[@AZExpert]

Thank you

[@jams19641996]

Rotate the height control valve. The valve can be used on the left and right side. It was installed wrong.

[@AZExpert]

don't worry I tried that

[@ceylontea5877]

Tagg axle vs single pro's and cons should be a good topic

probably not

[@gcflower99]

Great video! Gee, water damage on a coach from Louisiana (?) or points east following hurricane IDA? How could that be!?

[@AZExpert]

No idea...lol ;)

[@scottkellogg9736]

Are there any Class Cs in the 05' up to say 11' they stand out to you as better quality than most ? Tough question I'm going guess,lol.

[@DeSuperMan6]

Great video

[@robertsingletary3498]

I think the lines on the top of the valve are backwards. The pinched off line is fill not exhaust.

[@the_flores_family]

Those valves use to come damaged even when new,i almost went crazy trying to put a new one

[@AZExpert]

Yikes!

[@Melidontcare]

Enjoy your videos 👍

You need to do a road trip to WV next.

[@AZExpert]

lol I do

[@leewelbanks6366]

This is what you get when you get some so called RV expert/tech trying to repair something they have no idea of what they are doing. That coach is almost the same as my 06 except that I have HWH leveling.

[@AZExpert]

I run into it often

[@jameslowmanjr6141]

WOW. My air leveling valve went bad. My transport look like I was doing a reversed wheelie down the road. Until I got a new one easiest fix is level the airbags off and disconnect the controller arm. But 2 valves for all 4 bags. Something so simple. The RV companies try and improve it which just makes more problems. Sounds to me they tried to put a independent air suspension ride on that. The module that regulates each angle went bad. Then somebody that didn’t know what they were doing just got any air valve leveler and mounted it improperly. But it could just be bad. Because if you pull the lever or push the lever Air should be moving either in or out if it doesn’t replace it. Trying to find parts you could’ve found a truck repair shop they might’ve had an air valve most likely they would’ve but for that system it probably would’ve worked. Been waste of money and time.

[@AZExpert]

Glad it worked out for you. Thanks for watching! :)

[@zepe70]

@@AZExpert Touché, lol

[@ianm3343]

You could have plumbed all the airbags to the working leveling valve. Most semi trucks run all the bags on one valve.(also most semi trucks don't have that complicated of an air ride system.)

[@AZExpert]

I was in the middle of a parking lot, so I did what I could.

[@smacdiesel]

Wow, I'm starting to think these big rigs are just too complicated and expensive. You buy new and have poor quality issues. You buy older and the maintenance is so difficult.

[@hoofixrman]

I agree!!

[@AZExpert]

Agreed

[@gst69man]

you are appreciated! good vid

[@rickl6697]

Could you have adjusted the passenger side to ride a little higher to level it out?

[@hcrffi]

👍 Happy 4th of July! 🎉🇺🇸

[@scottmartin-r9j]

Did you find the problem?

[@CountryZorro]

Can anyone tell me where their shop is located? I am in Arizona and would like to get in contact with them for some work on my RV.

[@AZExpert]

I'm not currently accepting any work, but thank you! You can contact Cassones RV in Mesa and see if they can help you!

[@erasmolopez7814]

How about turning the valve around and moving the lever to the other side

[@Jimmy_Jim_Jim_1234]

Is there rust protection for rv/motorhomes? Like Krown?

A very bad habit I have listening TV , and watching vids who could be important as you show , but I put no sounds on, please add that ,in future vids !

I have looked into captions but unlike TikTok, KZbin makes captioning much more difficult. Hopefully, that feature will be coming to KZbin shortly.

Is there a spray on wax you recommend for RV roofs ?

[@raypage9035]

Thanks James for the great videos. What was the final outcome of the new ride valve?

@@AZExpert I spent 30 years doing production machinery maintenance with lots of pneumatics work. So I was curious as I have my suspicion as to what the problem might be

Really thinking the ride control valve is plumbed wrong. Exhaust should never come from supply, should come from bag only.

It's a hot mess

What's the best way to store a class A for weeks at A time when at home with shore power. With bags full ( Level ) or flat no air

Flat.

Got a question about a power gear slide out 2004 class A how do you know if it needs slide locks or not got it used slide comes out 2” when you drive it thanks

[@AZExpert]

likely you have a bed hydraulic valve or the brake on your electric slide motor is off

[@gregkiehl64]

There’s a break on the Electic motor how do you check out the break or do you have to replace the motor I hope not thanks for answering me questions

Is the ride height control part of the air leveling, or do all air suspension coaches have this setup? Was that the rental car you were following the coach in? How far did you drive it?

Thousands of miles
