We have the 235S with the Chevy also. Very little movement except if one of us goes to the head at night, I feel a little swaying. Don't really notice it with the door or door step.
I'd be VERY interested if someone has a levelling solution. I've been manually doing it with two bubbles and Lynx Levelers. Is it worth the cost to try to add hydraulic levellers "after market"? I looked at the trailer type levellers that mount to the bumper and have two jack posts, one on each end. They don't seem strong enough to lift the coach two inches or so to level it.
Looks like Camping World sells the HWH levellers as an aftermarket install.
