Lately it seems the stripped Sprinter chassis like the
WB-Via is the only realy shorty class-A. I have not seen E350/E450 stripped chassis utilized for class A's, but I have not researched that either. I have not seen but a few conventional class A's less than 30 feet.
The Tiffin Allegro Breeze 28BR is a very short diesel pusher with capacities galore, unfortunately lacking a clothes closet. That model measures only 29'-7" end-to-end. It offers so much in that short length.
CLICK HERE is see the Breeze on Tiffin's website.
To get a clothes closet you have to go with the 32BR adding 3.5 feet, not worth it to me, defeating the purpose of going short in the first place. It seems there are other means of getting around the lack of a closet.
