Thanks to the both of you. The PO recently had new tires put on this unit as they were going to a lake area in FL about twice a month. He gave me the receipt where he bought the tires as they are under a warranty. The receipt also shows that they re-packed the bearings too. The trip home was a good one, I started out pulling it the way he told me he has done this for a few years--with just the ball and sway bar. I didn't think so, and proved it was not for me. No sway, just the trailer rocking back and forth as if it were riding on train tracks. We stopped about 25 miles out to put on the DWH and all was well the rest of the way. I checked out the tanks this morning, all seemed dry as nothing ran out. I then ran the hot water faucets, WH off, just to run water through the system and put water in the tanks. I put cleaner in the toilet and ran it for quite a while to put liquid in the black tank. Then I dumped everything out so I could see what was coming out. Almost clear water with some green tint from the cleaner. The "she" seller told me she kept it clean. The fresh tank is now filled with some water and Hydrogen Peroxide in it (I don't use Clorox) just to sit a few hours, then I'll drain it, rinse it. The A/C was left on all night, too low, but works well. Fridge is washed out good, all cabinets are clean, I'm ready to take the Grandboys to a campground locally next weekend for a "shake-down" cruise.
