Do you guys have any suggestions on how to get the truck to ride a little smoother while pulling my 35'TT. It doesnt bother me to bad but the pregnant wife doesnt care for the experience.

I'm with her!! Alot of people are going to come back with " Its a HD" I have read that till Im blue! I just ordered a set of the Bilstein 5100 shocks. I'll try these if they do not help I'll convert it to air ride. If that doesnt help I guess that puts me buying another Avalanche and transplanting the DMax..:D

What's your tire pressures?
I keep 75 in mine, I'm sure if I went down to 50 or so it would be alot smoother.

I keep the front and rear at 70 psi. Im afraid to run to low and overheat the tires. Ive also thought about lowering the trailer tires but also afraid of damaging tires.

50 psi is fine in an empty truck. No tire heating issues, and a smoother ride.

I run lower psi when im not towing. Im talking about while towing a trailer. My old 21ft trailer seem like it rode alot smoother in the truck than the new 35ft.
The trailer weight and size maybe the issue.

Besides replacing the shocks, if you haven't already done that, I would find a way to put some weight in the bed of the truck. A 7k TT is acutally pretty light maybe 1k tonge weight...

The tongue weight of the trailer is about 800lbs. I guess I could put some equipment in back of truck instead of inside of trailer.

That's what I have found with my flatbed. I need to actually make my truck squat in the back (but I have week springs) before it rides nice. Otherwise it kind of has a choppiness to the ride.

I would bet that if you could get some more weight on the tongue or in the bed, you would ride a lot better.

You could always look at converting to air ride seats...........

This might be a good excuse to purchase a aux. fuel tank for the rear.:D

If the tongue weight is only 800lbs you can drop the tire psi down to about 60psi in the rear. My car hauler has 800lbs t/weight 60 psi makes it ride like glass. One other thing if your tires are at 80psi as you are towing/driving they will build heat and the heat will make the tire psi go up 10 to 20 lbs,
Also what does the ride feel like???

It feels like a sharp jarring (like a pogo stick) when the rear of the truck goes over bumps and the same feeling follows as the trailer passes over the same bumps. The front of the truck dont feel that bad.(other than being a HD)

Almost forgot what type of roads are you driving on black top,ect
In CA the freeways are concrete and the expancion joints are spaced badly and it makes your truck buck violently!!!!! Ask any body who lives in SOCAL and drives the 101 freeway, but if the freeway changes to black top the truck rides smooth as glass.

Will it ride like that empty?

It rides like a HD when its empty(rough but managable). The roads we usually drive down are blacktop farm to market roads.(not real smooth) The interstate is ok but certian bumps and joints just jar and make your boobs hurt according to my wife.(ha ha)

70 psi in front is more than you need. Try 55-60 up front-that is more than adequate for the front axle.

The tongue weight of the trailer is about 800lbs. I guess I could put some equipment in back of truck instead of inside of trailer.

800 Lbs? What is it, a U-haul? ;) My pin is 2000 Lbs. If your's is ony 800, I'm guessing you can back off on the tire pressure, or as you said add some weight. Look at the rating on the side of your tires for guidance.

Tom,
Yours must be a 5th wheel my is a bumper pull. Im going to try and lower pressures and see how that goes.

Consider one of these
http://www.airsafehitches.com/receiver_hitches.html#Class5 or something
similar.

I would love to use something like that but the hitch that is required to pull my camper is a 4-way Equal-i-zer sway control hitch and the head wont work.
The nose of my camper comes to the very tip of the frame so its impossible to use a regular chain style load equalizing hitch setup.

I have found these HD trucks need more hitch weight. Have you changed out the factory shocks yet? if not do so.
Level your trailer, the truck ball height should be about an inch higher. Hitch the trailer and level the trailer with your equalizer and see if that helps "the pogo stick" .
