So many good comments. Thanks. We have gone from tent camping to a 31ft travel trailor and now have a 42ft 5er. The 5er meets all our needs and is really perfect for us. We are entertaining going on extended trips in two years. We are considering a Class A because it just seems easier to get into camp sites. The Challenger 37kt floor plan is the only Class A plan we both like. Thanks again for all the input.
