I have a 2002 Adventurer 32V and we love it, our previous rig was a 1990 Bounder 27D and loved it even more but stuff was falling off due to exposure.
I don't think the 2005 is a Chevy. Go to winnebagoind.com and look at the sales brochure for all the specs. You can also download all the electrical drawings and parts catalog for the Winnie.
I also am tired of leveling with blocks and the hydraulic levelers are a wonder, the slides open easily and provide so much room.
One thing that was a problem in the Winnies is the front coach heater motor is a pain in the backside to replace and they don't last very long.
Download the sales brochure and check it out. I disided to check the engine on the 3510 just for my own edification and it appears there were two Fords and three Chevrolets for that model.
