Well said by axis earl and bigben. RVs are quite expensive if you aren't using them. Depreciation will eat up the value and the loan interest or opportunity cost goes on. (That applies to boats, planes, cars, most vacation homes, etc, too.)
The RV lifestyle is not for everyone. We know a couple that bought a new Class A, their first RV, fixed their car to tow, and took off on a trip. When they got home, they sold the coach back to the dealer and went back to car trips.
All things considered, including depreciation, it costs us a bit more to own and use a RV to travel, but we meet more new friends, eat in fewer restaurants, see more interesting countryside and don't have to lug our suitcases at every stop. Oh, and we don't worry about bedbugs. To "newbies", what's that worth to you?
Bad decisions make great stories!
