Welcome, and good luck with your RV. You will most likely find that issues will come up even if it is lightly used. The mileage indicates that it most likely sat for long periods of time. The tires are almost guaranteed to be out dated and need to be replaced before you do anything.
I hope you get a reliable inspector to go over the entire rig to give you an idea of what you need to do. All things can be repaired or fixed but only you can decide the value of the entire package.
Good Luck and happy camping!
Enjoy Life! It's later than you think. Life changes in a second. There isn't enough time for cheap booze and cheap cigars.
