“Get the RV that you'll be happy traveling/living in. There are plenty of parks you will fit.” Very good advice and in 14 years at 42’ I’ve never had a problem or any dings if some scratches high up do not count. In Yellowstone my 42 became a 40’ (never been measured) .lbut I doubt I can stink my 45’ that much. When not snowbirding we boondock most of the time...do you really think I’d go to 45’ if it was??? Sure it’s harder the longer you go and no I would not recommend 45’ for most people but 40-42 gets you big tanks and nice features to go glamping. Most of the CGs we stay in do not have a host and you put your money in a post.
