Sharp Bouncing
Morning. I have a 2015 Chevy 3500 HD short bed, Crew with the duramax. It's setup with RS9000's in the rear (set at 9) and stable loads. Front shocks are Bilstein 5100. I have a Hellwig stabiliz...

I am sure it is road surface induced. It only lasts a second or two and it doesn't happen all the time. The strange thing is that I don't FEEL any bumps in the road when it happens, and it recovers quickly. The larger dips and bumps are handled fine.
I was going to try to lighten up on the RS9000's which are set at 9, but I thought that might be worse. I'll move them down a notch and see what happens.
I don't know the rear axle weight yet, but I am sure I am at or slightly over the limit of 7050. I plan to weigh it Columbus Day weekend at a CAT scale.
The camper is an Arctic Fox 811S. Center of gravity is over the rear wheels. Yes, I know it's a 4300 pound camper loaded. I'm very happy with how the truck handled except for the annoying choppy bounce every now and then. It didn't seem to matter whether I had a full 51 gallons of water or not - I tried full/empty and not any significant difference.
I am really thinking it's induced by the helper springs being loaded like they are.
OR, it could be the way the camper sits in the bed. This truck has a large lip at the forward end of the box, on the top of the bed. The rubber bumpers on the camper barely touch the front of the bed, and the exterior wall of the camper hits the lip. Bad enough that it squeaks and on this trip I had to grease it or I would have gone crazy. I am going to have to modify these rubber stops on the camper to get them out another inch or so to keep the camper off the bed rail.
Finally, I have a rubber truck mat in the bed - maybe there is some give to that?
What about adding Cabover struts? I have heard pros and cons, but generally people say they help.
