I'm interested in Chevy chassis feedback as well. I test drove a Forester 25' Class C two days ago - it was quieter and I was able to get it up to 65 and steer w/ 1 finger on the wheel w/o suspension mods, helper spring adjustment, alignment, etc. A refreshing experience and one that frankly surprised me.
Also the bumps and dips in the highway were 100% different. The Ford more or less banged through them for lack of a better way of saying it, the Chevy floated over them and rebounded like a old school Grand Marquis or Caddy.
Quieter in the cockpit, more room for the passenger. I enjoyed my test drive. I'm sure you can't put the Chevy on a 32' rig, but the 25' rig was perfectly happy. Chassis wasn't stretched either - factory 159".
