As well as length, you probably want to take a look at the room inside. alloy, above mentioned opposing slides and that would be one thing I would want in a rig I would be spending a lot of time in since they open up the FW tremendously. I think, that with a little research, you would be able to find a FW less than35-36' with at least three slides, two opposing in the living area and one in the bedroom. However, every slide that goes into a FW increases the weight of the FW, so you would have to factor that into the tow vehicle that you will have to buy as well. Good luck on your search.
