I also have a 2005 Ambassador with a hundred and five thousand Plus. It has made three trips to Alaska a trip to the west plus many trips to Fla. Expect normal things (tires, batteries,windows losing their seal ) but the main thing was a leak around the plug of the fuel tank after about ten years. About 3 or 4 tablespoons in 24 hours. This left a stain in Wally'world parking lots.
We we were able to get it welded in place with out dropping the tank. Also we are on our third set of tires. All in all it has been a good coach.
