AF also uses "full wall slides". Their single "slide out" can be as large or larger than some of the double slide out TCs. A lot of the TCs that utilize a single slide have just a partial part of the wall that moves out, usually just the dinette seating area. On my AF 1140 the dinette, the stove, and all the curb side cabinets are within the slide out, opening up a very nice living area. Dont worry about construction either by having a full wall slide out compromising wall strength. My AF is by far the best built RV that Ive owned and its my 4th one.
