We also went from a 32 ft to a 40 ft, I actually found that the larger trailer is easier to back up than the smaller one, if you are comfortable backing up a 5th wheel you probably won't see much difference. I too have gone to an axillary fuel tank and now either fuel at truck stops or drop the trailer and fuel. I can't say that the extended length doesn't limit where you can stay, but it certainly nice to have the extra room if you are on the road for extended periods. We certainly enjoy the extra room.
