We have a 38J. We use it about 6 months out of the year. We love the floor plan!!! 36,000 miles on the workhorse W24 chassis, no problems. Crossed the Rockies several times. Plenty of power. 8.1 MPG. Love the basement air and trunks that come out with slides. Wish Winnebago still made them. Hope the one you are looking at has been well maintained.
As I have said before the tank is a waste of space and money. If you have to buy a compressor with a tank get rid of it. You don't need a tank to fill tires!!! You need at least 125 psig compressor. The higher the cfm at 125 psig the faster it will fill the tires.
Maybe it is just me, in the RV clubs I belong to and the RV parks I visit Most Class A owners are OLD. By most I mean 99%. This has had an effect on membership in Clubs like FMCA and WIT. Are there any young folks out there?
