All I can do is give you the dimensions for my coach which may be different for another rig. My wide body Monaco is 102"(96" inside) with 12" on each side for the mirrors. This gives a total outside to outside dimension of 126".
You say that you have exactly 11 feet(132"). Obviously any windows or anything else that protrudes from the walls will have to be considered.
Basically if you have a wide body Class A coach you will have 3" to spare on each side. If you get one of the narrow body Class A units, this will gain you an additional 3" on each side.
Not ideal and with care it could be done. You will have to take your tape with you and measure any RV that you plan to buy.
