My wife and I will be retiring in the next 4 to 5 years and want to do some traveling in the U.S. (National Parks and other sights). We are planning on buying something in the next couple of years but don't really know the pros and cons of each type of RV. If anyone has any experience with RV's (class A, class C, Camper or 5th Wheel) if you could pass on some experience and thoughts I would appreciate it.
