5th wheel chucking

Hello everyone, 

 

Seeking sage wisdom and knowledge.  Just upgrade from a TT to a 5th wheel.  My Silverado is a 2024 2500 LT with the Z71 package.  I install a curt rail kit and utilize a curt a20 20k hitch to tow a Grand Design 298bh, estimated weight of 10k with 2k pin.  
 

My issue is chucking.  Everyone has commented that it must tow way smoother than a travel trailer, but my experience has been the opposite.  Any irregularities in the road surface, any acceleration/deceleration causes the truck to have a push/pull feeling.

 

I am looking for potential solutions.  I’m going to shim the feet of hitch with rubber for isolation and take any slop out of the rail connection point.  Would airbags for the truck help?

 

thanks in advance

I did something similar with my B&W hitch.  It used to rattle a bit over bumps in my 2022 2500.  It was installed by the place I bought it from.   When I moved it over to my 2025 3500, I

The feel of a TT vs a 5ver are not the same......

 

My grand design reflections 273mk, is just under 10,000.  It tows and feels different than my TT did. And, i have never used weight distribution yet on a trailer.

@lineman1234 I expected a different feel, it would have to be with how the weight is positioned on the truck, just didn’t expect to get beat up more with the 5-er, what hitch are you using?

Looking at your first picture, your 5th wheel is quite a bit out of level. The nose looks noticeably higher than the tail. I would lower the hitch head (not sure if the curt allows for that) and/or raise the pin box so that it sits level. That may help smooth out the ride and you still should have sufficient clearance.

The front of the camper should be 6" above the bed. Yours looks higher. Also, have you actually measured pin weight at a Cat scale? Specs are dry weight, add all your gear, propane, batteries, etc. Granted, your 3500 should handle it fine, but you'd be amazed how fast it adds up! I plan on bagging mine for my 5er we're buying.

I hear that. Can’t wait to put the GD 32BH behind the 2500 to see how the 6.6 gas pulls compared to the F350 7.3 I had. It’s going to be a great camping season.

My fiver started the hucka bucka on the way home from Camping World.  Called up my buddy and he said he always pulls his fiver with a full water tank.  I filled up the water tank, added a second battery, put in all the equipment in the storage compartment and the bucking is nearly eliminated.  19th Ave in West Fargo could get my trailer bucking anytime no matter how it was loaded so some roads at lower speeds may induce the issue but for the most part I'm happy.

Does your hitch rock in the bed rails without being hooked to the rv?  You need to get that play fixed.  Loosen the bolts and press on the hitch to get it settled, then slowly tighten the bolts. I have had others tell me to hookup to the rv and then Loosen the bolts. The weight will hold the hitch down to tighten it. Just make sure the tow vehicle and the rv are not pushing or pulling at each other. Need them relaxed. That's why the puck system is a little better. You have adjustments on each corner.

I don’t have screws bolts that hold it to the rails, just pins, I did shim the attachment points, but need a thinner one to add onto..1 layer isn’t quite enough, 2 is too much of course

No, the bolts that hold the legs to the center section. You have the same hitch that I do. But I have the puck system legs. There's 2 or 4 bolts on each side. I can't remember if they take a 3/4" or 1 1/16" wrench. I think it's the 3/4" wrench. The 1 1/16" wrench is used on the pin box bolts, I think.

      Still looks like a rivet to me in the pics, I don't see a nut and none of the pics show the head of the screw. But if you says so.....

      Tire psi

      By jgaudet99 · Posted

      Thanks for all the help so far!   I did try right from 2026 right down to 2021, and only from 2023 down lets me select the option for tire psi change, but I get the vehicle not supported error!   I'll definitely try it under Chevrolet after work today, and I'll get the sensor number from gm for my truck tire sensors. And I'll let you know if it works for me under Chevrolet!   And if that doesn't work, I'm going to guess that what @Atlas said about maybe I have a different body control module could be true!

      2010 Avalanche 5.3 not running correctly after engine swap.

      By Jsdirt · Posted

      From where I'm sitting this sounds like a compatibility problem. I'm assuming the 2007 was a 900-series truck, and not an 800-series (they were sold side-by-side in dealerships that model year), since it starts and runs.   This is why I HATE post-2006 vehicles. Everything becomes a huge problem when you try to keep the thing running for longer than the manufacturer has designed it to.    I can't remember when Global-A architecture started - either '10 or '11. For your sake, you had better hope it's '11, or you're going to be spending some BIG money to correct this cluster-eff. That's something you need to find out before doing anything else. You may have several computers bricked ... but the fact that it runs tells me you MIGHT be ok here.     EDIT: Just did a quick refresher. You're screwed. This is Global-A. The 2 systems are NOT compatible in the slightest. Once you get the correct engine in there that IS compatible, you're going to need to see how many computers are locked. Absolute NIGHTMARE to straighten out, too. Your buddy might be better off cutting his losses and finding something else.   Welcome to post-2006 vehicle electronics. This is why I quit the industry, and drive nothing built after 1994. This stuff takes all the fun out of wrenching!

      True, hard to say what differences there may or may not be between Chev and GM as well as a production year or mid year part change either.    I just found it odd that under the Sierra choice on the Autel that many of the last few years of production year did not include the choice of changing the tire pressure but if that is an Autel thing or a GM thing as to why the choices were not there. Knowing what tpms sensors are on the truck should give some guidance into which choices on the tool even make sense to try as I wouldn't give up just yet with the tool but I guess he will see what if anything he comes up with if he finds out a bit more info and tries a few more things on the Autel.
