Newbie looking at used coach

Update! I bought it! The guy that sold it was the original owner. He is around 70 yr old and seems like one of the most honest person I ever met. A real old school type. He said he thought of retiring and bought this camper, drove to Florida and back, never used anything except for the motor to get down and back. He decided retirement wasn't for him and went back into his machine shop stored the rig in one of his heated warehouses and went back to work. He is bringing it back to the dealer where he bought it and is having all the fluids changed and having anything, anything thats wrong fixed. He was that type of guy, whatever the cost! He just wanted to do what was right. I felt very humbled, it not often you still meet someone like him. Thanks for all the advice! Now since I've never even been in a camper until now or even camped before, the adventure begins!! Hang ON
