When you really put the money on the table most often it doesn't save any money. You figure the increased fuel use, insurance, upkeep and for some storage, and then the cost of the RV (25k) . You can get a pretty nice AirBnB and be dang comfortable with less stress.
If you want to stop you won't be needing to worry about traffic or getting in and out of parking areas.
Those RV payments and possibly the new tow rig still need paid in the off season.
The prices of RV spots in a campground have gotten ridiculous in many areas. Often I seen prices at an AirBnB for near the same.
I've seriously considered buy an RV a few times as I grew up traveling to places and camping with them. Anymore I just can't talk myself into it.
