2016 GMC Denali 3500 Dually, crew cab, long bed, duramax with 2017 Host Mammoth. Already has airbags and Stable loads (upper and lower). Air bags keep the rear sag to a minimum. The problem is expansion joints and the wonderful dips the “engineers” have left us. The truck seems to leap, so I’m assuming this is what is known as a rebound issue. I imagine that the truck is compressing into the overloads as designed, but hopping back out.
Do I need front and rear shocks? Bilsteins? Rancho? Some post seems to indicate that the nose (front shocks) may be issue ...
How does one learn the wheel weight capacity? My inner rears are steel (i think) and the fronts and outer rears are (what looks like) polished aluminum. Stock tires are little 17 inchers.
Slide ins are not for you.
Sorry.
What you are experiencing is pretty normal for loads like slide ins, kind of like "porpoising" bounce. It is due to road harmonics interacting with your vehicle and your load center of gravity.
You have a slide in that weighs around 3300 lbs empty and it is placed HIGH up on a 4x4 truck platform, it is going to wiggle and jiggle and there is nothing that you can do short of welding the suspension solid to the truck frame.
Save your money, you already have tossed plenty down the drain.
