Got a new to me 23 Sierra 2500 slt crew cab 6.6 gas 28k mile, snow plow, and camper package. Pulled my 26' bumper pull camper for the first time and it pulled great except the truck bucks like a bronco on surface roads. Rides ok on the highway but no where as smooth as my last truck. My last truck was an 03 Sierra 2500 slt extended cab 6.0. Anyone have this issue and solve it? Could it be just needing shocks? I don't use load level or sway hitch with the camper, I did not use it on my old truck either and as far as ride goes the 03 was a more comfortable ride no bucking.
