Let me be the first one to Welcome you to RV.Net! Glad your here and you asked some really good questions. I just wanted to suggest to you what an "Old Boy" suggested to me when I first started RVing in 1976! Don't buy any coach smaller then 24 feet, pick out 3 RV's that you like, then narrow your search down thru : #1. Budget, make one that you can live comfortable with and stick to it no matter what. #2. Go with the RV that the floor plan best suits your needs. #3. Colors, engine, transmission etc. Happy Trails and have fun RVing.
