New 5th wheel doesn't tow well

BULL! Put Airlift airbags on the rear and Firestone airshocks on the front and measure the ht of your Truck from tire to fender. Hook up and air up until they are back to the height they were before and drive it. Call it chucking if you want, it's bucking, shocks aren't heavy enough to stop it so it goes down to the stops and then bounces again I know it will alleveaite the problem. I'm on my 3rd pickup with 5th wheel and airride. I have never had 1 problem with airride in 15 years. I don't know why someone who didn't put airride on the front would tell you it doesn't work. (Chevy 2500 Duramax Allison 6spd 420 Hp.) Chucking is aword thrown around by amateurs who own TTs and it isn't even in the dictionary.
