We just moved from a a B to a C - needed more room for the wife and the dogs! We found that the smaller C units were on the Chevy Workhorse base. Since then I have learned that the Chevy has a smoother ride, better mileage and a LOT more leg room in the cab. I am not a chevy guy by any means - but it may be something to consider.
The previous owner of our Tioga modified the bathroom wall\door to match the length of the left-rear queen bed. Lots more room in the bath - lost some closet space, but we are OK with that. Now we can dress in the privacy of the bath - important to DW.
Good luck in your search!
