I spent lots of time researching motorhomes with widths of 96 inches or less for our recent downsize from a class A. Phoenix Cruiser makes a great coach, but we couldn't get at least a queen sized bed without going to 30 feet. Nexus Vipers are 96 wide but again had to go to 28 plus feet to get a queen bed. Coach House are 96 but much more expensive. All of the Sprinters are more narrow if you like diesel. A Forest River Lexington is 94.5 wide. The Winnebago Trend is 90.5. The diesel Winnebago/iItasca Via and Reyo are 90 inches wide. We decided on the Thor Axis which is a class A on a C chassis. It came closest to meeting our top requirements. It is 94 inches wide.
Hope these will help you in your search for your perfect coach!
