Thanks. I was going to have the brakes looked at as part of the tune up and oil change. The tires were new the last year we really used it so the tires are about 5 years old but I understand what you are talking about and even though they look new, I don't think I would trust them more than driving them to the shop that did the work the last time which is luckily only about 7 miles from where I have it parked.
The gas is one of the reasons I was trying to run it to try and burn out the old and then get some fresh in there. I'll have to take a look at the roof but probably will need to be re-sealed.
We are getting to the point now that we can start using it again so I'm trying to figure out what I can be doing between now and the spring when we would start camping again.
