Can I get 35' 5th wheel into a lot of natural spots?

Wow, thanks for the help. I have very little experience towing, and it's not my idea of a good time. But I'm sure I can master it with some practice. This is one reason I think I'd be more comfortable in a 5th Wheel over a TT. (I have read that with high-end hitches, a TT can be as smooth, but still gravitate to the 5th Wheels).

But is there any reason to think a 30' 5th Wheel would be much easier to navigate than a 35'? Or would it open up more options in state/federal parks?
