Shop around before you buy from these guys. The sales staff is very helpful but when it comes time for customer support after the sale, be careful.
I bought a "used" 2018 model class C in 2018. I expected them to go over the unit thoroughly before I took possession. We found the house batteries did not function on day one. It took about a week before I could get them to replace it while we were on the road.
While traveling, I found several other things that did not work as well. Their warranty for used vehicles is worthless. I took my rig in for warranty service and was told that "pre-existing" conditions are not covered. Duh, everything on the unit is pre-existing when you buy a used vehicle.
When something goes wrong with electrical or mechanical, that may not be covered. What good is a warranty?
