Yeah, this is not a smart money hobby. It cost a lot with no return and lots of depreciation. But if it is something you enjoy and/or love its great memories that are priceless!
Dave Ramsey would probably never never recomend rving to anybody unless they had millions in retirement already. This great lifetyle is probably never going to make money sense, but we all have our vices.
-if its all about the costs of camping dont get started, because it adds up after a while.
Good luck on your decision!
