Limitations and access issues of 40' or better?

We weren't sure about an RV when we started. We rented a class C for two weeks to try. We then bought a six year old 33 foot gas. A year later we traded up to a two year old 36' DP with two slides. Three years later we traded up to a four month old 40' DP quad slide, our current coach for the last six years. Don't regret the move up and this coach is as easy to use as the first gas coach was.
