Kentonjm, We have the 2002 Adventurer 32v with the Chevy engine. We actually went to Scottsdale, AZ to purchase it. The one thing we needed to know before we bought it was if it would pass California smog. So before we started over to look at it the owner took it into California and had it smoged. Once that was done we started our trip to AZ.
I can look tomorrow morning for you to see the size of the bins, also there is a lot of storage under the bed with the lift up platform. Don't know if that would help you out.
Another thing, is the basement air which I really like but it does take up more bin storage. We are not fulltimers so that is not an issue with us. Hope this helps, will get more info for you tomorrow.
