That coach has not been maintained and the dealer will take every possible shortcut possible to make the sale from your description.
If you continue have an independent inspection including engine/oil and cooling analysis. And you do this not the dealer. The dealer will put in used/refurbed or cheap batteries. Monaco used BadYear tires and I replaced them on both coaches so be prepared to replace them. Another expensive repair/replace item is the refer.
The AquaHot can be very expensive to repair. Do all the registers work? Does the hot water work? Does the hot water work from the engine if so equipped. Does the AH heat the engine for cold starts if so equipped. Is the exhaust smoke free and diesel oil free.
The gen can certainly be another big ticket item.
The CareLess toppers and awnings tend to have issues.
But of course any older coach will have issues.
Several years ago I bought 2 Interstate GC2 batteries in Phoenix. Stamped into the case was the date which was 1 month old. I knew the batteries were made in Mexico and they are doing well in my sons 5er even with a little abuse.
