Backing into a campsite with a steep approach angle (90 degrees or less) is more difficult with a longer TT. We ran into this a few times with our previous 34-footer. Once the turn is actually made, however, the longer trailer behaves a bit better, taking longer before it starts heading off in a direction you didn't intend, than a shorter trailer does. What you may find is that your campsites are limited, especially in national & state parks, due to the length of the TT. Many of those campsites were designed years ago, when trailers weren't that large.
