In 2013 I purchased a 2000 Thor Hurricane with 15,000 original miles and the generator showing 7 hours for a very good price. I have now over 18,000 miles and have had to fix some very small problems.
I have spent less than $100 on the small issues. Oil filter and oil for the V-10 engine and oil filter and oil for the generator.
The carburetor on the generator just needed a cleaning.
The heater had dirt dauber nests that needed to be removed (I installed the screen covers to prevent that re-occurrence).
The drain valve for the fresh water tank needed to be replaced (old plastic crumbles).
The LP gas regulator was replaced due to a small leak.
The larger things that you will eventually have to cover, I did those also. New engine battery ($120) and new tires ($3,000).
I bought new house batteries for my Truck Camper and moved the 3 year old batteries to the motor home where they have been working just fine. I don't dry camp in the motor home but do in the truck camper.
Things I have done that were extras: replaced interior and exterior bulbs with LED bulbs. Added backup camera system. Swapped tube type TV for flat panel TV. Added a Blue OX track bar. Replaced differential fluid. Added K&N air filter.
Be prepared to spend some money even if you get that once in a lifetime buy on an older motor home.
