Is a 40 foot fifth wheel too long to access neat places?

We also hike, kayak, and bike. Not full time yet, but we have the rig set up and waiting to go. Even our 32' is limiting in some places. I cheat and put 30' into the computer for reservations. I find that with our previous trailer when I could put 25' in there were often significantly more sites available. I can't imagine a 40'er. The indoor living would be nice I'm sure!
