I have a 3500 dodge ram pulling a 35 foot travel trailer touque weight about 1100 lbs the back of the truck squats when I hook and the bouncing hurt my back. I had new shocks put on before we went on a 2500 mile trip it helped some. yesterday I put firestone ride rite air bags on. the difference it made is great. I still feel bumps and rough roads but the air bags smooths out the ride and I don't get the bounce like I had before.
I used to own a Rockwood Signature Ultralite 8285 5th wheel. Any it didn't move my F-250. See picture
Something weird I must say with the truck.
I see you have a Signature Utralight which is quite light compared to other trailers. I wouldn't think it would make the back of a Chevy 3500 even move. All I can suggest is get it weughed at a CAT Scale to truly find out whats the issues.
You didn't do anything to the truck leaf springs or remove any?
Have you owned the ruck from new or bought it from someone else?
Good Luck
Could be that the 5th wheel was installed too far back in the bed of the truck and all weight is on the rear axle with no weight transfer to the front axle. If the dealer installed the 5th wheel don't think that they didn't get it wrong.
