Went down and messed with the diesel pusher. Tires are dated 2010 so there's $4000 of expense.
Batteries were still charged. Turned the refrigerator on and left it on to see if it works ok. Played with the outside tv, cd/dvd player, and radio. Played with the living room tv a little. Haven't checked the bedroom tv yet. Dashboard cd/dvd player worked.
Still have to check out on board 10kw generator, hydro hot (it heats the domestic water and also is the furnace either through forced air or the heated floors whichever you choose, runs off diesel or electric). Have to check out the sanicon, it's a sewage grinder that pumps the waste to the campground drain out of a 1 inch hose.
Put water pressure on the plumbing to check for leaks.
This is turning into a lot of work for something I'm thinking of buying.
