I purchased our 2002 Ultimate Advantage 40J four years ago and it was a low mileage coach. Working with the dealer we had all oils, water, hydraulic oil changed, transmission serviced before delivery. Also purchased an Extended Warranty and that was to our advantage with repairs required.
Due to the low mileage we have had engine issues with the lift pump, HWH leaks and 12 volt motor, and many small items. But overall the coach has been very comfortable to ride and live in.
I would advise the OP to devote time to go over the coach from front to back, service all systems and pay close attention to the roof and all seams. Use the Dicor self leveling on all seems, wash it, and apply a good protectorant. Never use a silicone sealant on any part of the roof or around any window. Check the Winnebago web site for the list of sealants with part numbers for the 2000 year.
I would wish him many happy miles in the coach.
