This RV has only been used a few times. Stero system and speakers upgraded 3 years ago. Upholstery on drivers, passenger, and sleeper sofa done 4 months ago. The mileage is correct, 3400 or less. The RV has been inside of a building since the day I bought it, I have not left it outside except when we used it. I have had RV checked out and serviced 2 weeks ago. RV is in excellent condition.
