How much will a big fifth wheel limit us?

What got my attention is when you said you wanted to be out in the boonies a lot in Nat'l Forests, etc. My opinion is that you should limit your trailer length; possibly to 30 ft preferably less and even that can be too long for some campgrounds with sharp curves and short sites. You can get along with much larger but with a lot more planning and making sure you know what you will be getting into in a campground before you head down a gravel road to a remote campground.
