The weight capacity of the rear slide on a 235RKS is 1,000 pounds. (verbally from our dealer). Yes, it can be used in the retracted position without any issue; I do it all of the time. The 235 is about 3 feet shorter than the 264 which will help your TV situation. However, it is not really much lighter. Our 235 weighs about 4,500 pounds dry (factory sticker) with option. FWIW, we love our 235. Criticisms: A lot less open floor space than a 264 (not as good if you have kids/dogs); storage space is light. (although there is the whole bunk area if you are not using the lower bunk) Advantages: Tows awesomely well, ability to fit into most campgrounds/sites (even remote forest service), lots of utility for the size. Good luck; be safe; have fun.
