Hi. Right now I'm motor homing vicariously. If and when, the unit would be a 5 to 10 year old A or C not longer than 30 feet, preferably with a Murphy bed, and gas engine. I would be a full timer, tour the country for a couple years, put 15,000 miles on it, and sell it for 80% of what I paid and put into it. Of course, any return on the sale depends on if bought at a good price.
