Thanks Bob!! That's something I forgot to factor in. My heaviest loads won't be quite as heavy - but definitely more precious. My 5yr old Grandbabies!

I've met "Reg" from rcp...he makes quality parts in the good ol USA...

[@KJ6RSU]

I know I am 8 months late watching the video, but I wanted to say Thank You and to give you a thumbs up 👍 KJ6RSU Dennis 73 and Clear

[@HobbyconceptsLLC]

No such thing as late, just when you need it! KF7SCD

[@joeyclark789]

Kinda funny you put this video out because I was looking into the same thing for my dump bed. A dump bed with material overloads your truck pretty quick too. Great video as always.

[@montwolfman]

FYI...I thought you might appreciate trucker terminology to describe certain parts. The "flex" in the truck suspension is referred to as "articulation". The "tongue" of the lowboy trailer is called a "goose neck". If the goose neck is detachable from the deck, it is called a RGN (removable goose neck). Appreciate your very informative and helpful videos.

[@HobbyconceptsLLC]

Thanks!

[@FTWBIFY6667]

Very interesting! Thank you for the amazing information !!!

[@rookie101_]

Reg makes some awesome parts.

[@HobbyconceptsLLC]

He sure does!

[@JohnJohnson-qg2ub]

That is one of the coolest thing I ever saw in life. Thank u sir.

[@Raptor50aus]

Great video Bob, loved it!

[@robertschmidtrcmodelboats6483]

This was a great video and you are always helping to make trucks better. I hope to get my first truck soon, maybe the King Hauler.

[@ourr.c4065]

Fantastic video Bob.

[@stevesrandomadventures9066]

Great video thanks for the info

[@boostjunkieMike]

Great informative video. Thanks for sharing. Love the channel. Some more future upgrades added to list.

[@Maddogtrucking]

Great vidoe 3 things 1. the rc4wd lowboy is to low at the nose out of the box. the gooseneck should have been made so the deck is up about another 1/2". people have made delrin plates bolted to the neck that lower the king pin hight and raises the deck up. 2. flip the 5th wheel mounting plate around to put the 5th wheel ahead of center of tandems. this will put more weight on the steer axle and it will steer better. 3. cut the tractor rear axle stops off and you gain about an 1/8" more travel. you need to upgrade the driveshafts for the extra travel. regardless pulling that weight the stock u joints/ driveshafts will quickly wear out.

very cool

[@rcdoebbora8086]

Amazing car truck

[@dirk2225]

Greetings from germany, good videos keep it up. 👍👍👍

[@crazycain1984]

Been wanting to demonstrate the power of these trucks to my neighbors by pulling myself with my Knight Hauler, but due to limited $$ I can't really afford those upgrade parts you show, so I have to diy most of it. Luckily alot of the parts are relatively simple design making them quite easy to make at home using just basic hand tools in most cases. Other than the 3rd lift pusher axle & more powerful motor i installed, I also strengthen the dampers & Leaf-springs, plus I'm using a jeep-dollie to distribute the weight of both the counter weight (for traction help) & tongue of wagon I'll be setting on. Should work (HOPEFULLY) LOL.. Great video though!

[@jiml9692]

Great idea... I have the heavy duty suspension kit from Rc4wd and rc4wd roady tires and I have no problem hauling around my bulldozer from rc4wd and plus I have 4:1 reduction bolted on the 3 speed trans. Nice video.

[@CarminesRCTipsandTricks]

The 4-1 Gear Reduction Unit made MORE of a difference in my Grand Hauler than anything else!! I use a 35 Turn Crawler Motor that actually HAS Torque (unlike the 80t which has MUCH less Torque - it's just slower!!)😖 It crawls at a Snail's pace in 1st gear.

[@jiml9692]

Nice... I'm using a 45 turn motor with the 4 -1 my driveway is a little steep and the grand hauler with the lowboy and dozer a mire 90lb's pulls with no problem. thanks for the reply.

[@r.ccustomtruckingsydneyaus4632]

it will walk over obstacles easy now but the trailer will drag on ground. i would change the hitch contact point on trailer to make trailer sit higher as well

[@mikewinans9953]

Hope we get to see that truck fully built

[@stephenkelly8065]

I have the same trailer and had the same towing clearance problem even with modified suspension. There’s a great 3D printable spacer that fits on the RC4WD trailer hitch, problem solved ! Part is on thingiverse. Cheers, Steve.

[@alexwenzel6932]

Always love your videos and what your doing for the hobby. The tires your using where did you get them from? I see there are 20mm, 22mm and 25mm tires. What size are you using ? Also where did you get those foam inserts ?

[@kingjamesiii4886]

You should make a peterbilt heavy hauler truck with a working tag axle!

[@CarminesRCTipsandTricks]

One note, Bob.... You've definitely beefed-up (eliminated) the Springs, which will certainly handle the weight and then some. BUT, the very weak link is that long, soft, Phillips Head Screw holding the Tandem assembly to the Chassis! I would seriously consider a 3mm Threaded Rod, of Titanium or Stainless Steel.

[@bamabiker750]

I noticed that as well. Ti or SST would probably handle the increased loads okay but would it be even better to step up to a 4mm bolt? Might need to pass a drill through the parts but it looks like there's enough material to accommodate a slightly larger bolt. Anyway, it's just a thought.

[@CarminesRCTipsandTricks]

@@bamabiker750 Going to 4mm would be even better. Even a less expensive Steel 4mm Bolt would be considerably stronger.

[@RafaelPacheco-wh6zs]

Hola puedes indicarme si puedo utilizar un los boy 1/15 en un tamiya 1/14 o cuál es la diferencia saludos

[@richardmckinney8354]

Sir, Do you sell assembled right ? I really enjoy your content.

[@thatsmyrc]

I've got the trailer and excavator. the simple solving solutions too all the problems by getting a beefier rig like the overland. dollar for dollar its better cents.. Ive also added different wheels and rock tread tires to the trailer. you will gain better clearance by far and have better stance on trailer, the overland can pull so much more weight as even it has metal axles beefier suspension 6x6. I was just pulling my 95lbs daughter around house on lowboy tonight. What I would like you see you create is a quick release gooseneck that can lift the dead weight of the 360L or the dxr2 8-)

[@thatsmyrc]

Ive got the lights in trailer it does make a sweet glow on road I removed the junk mud flaps and added proper true rubber ones. nice video Bob

[@HobbyconceptsLLC]

Thanks! Will be doing a video on lighting the trailer later. Will use the new Beier Bluetooth trailer light module. I agree on the mud flaps.

[@socalsean3425]

Can you please explain how to remove the MFC connectors for the lights Tamiya needs to make this easy As I just broke one

Hola donde puedo conseguir esa suspensión

Hi. My 360 has a lot of play on the cabin rocking up and down. Have you solved it?

Hi Bob, your video's are great, thanks....I have one question: In these video you get the hard inserts, do you have a link of these inserts? Best Regards Ron

[@HobbyconceptsLLC]

They come with the tires.

Hey Bob, where do you got the back aluminium suspension from? I like to put it on my tipper

[@nathankitts1903]

Bob, will that RC4WD lowboy trailer fit your HEMTT?

[@nathankitts1903]

@Dave N A lot of the engineer units I see use the M870A3, which looks very similar to the RC4WD lowboy. I know Bob made several videos of him making the old school M870 lowboy with a gooseneck that lowers for loading.

[@markhufnagel2744]

How about an out door video where you operate your equipment out side and show how it really works !?

[@HobbyconceptsLLC]

I really would like to do a video like that. Probably will next year sometime (when the weather gets warmer!).

[@CarminesRCTipsandTricks]

How about organizing 1/14th Scale Truck Layout Meet - like Europe, Asia and the UK FREQUENTLY have?? 😁🙏 It's almost sad that we spend so much time and money on these, and can't have the same enjoyment as half the World has.

HUH???? 😳

Where would a guy get the plate and fifthwheel from

eBay

[@brianrutherford3681]

Very cool.but why not put bigger tires and wheels?most heavy haul semis have taller tires and wheels to help with ride height on the trailer.
