As you are new to RVing I would say pass on the RV.
A) High miles to me.
B) While it appears to work you do not say you have seen everything work. There are a lot of expensive to replace items in a motor home. Refrigerator can run over $1200.00 to replace. Generator can be expensive to repair or replace. Does the hot water heater work? What about furnace and A/C both dash and coach. Water system check out and holding tanks hold waste.
How old are the tires? If over 5 years old I would replace them as you do not know their history. Count on spending at least $1500.00 for 6 tires.
You do not have enough information in order to make a intelligent decision
If all systems work then it may be a fair price
