Great advice! We did our walk through this afternoon and came back much more comfortable with our decision. The issue of tires lead us to ask many more questions about how much it was driven. Thankfully, the seller explained there were many short trips to the local casino for overnights in the parking lot, many weekend drives just to get it out on the road plus a few extended trips to local attractions/campgrounds. So it was not just sitting in the sun. They appear to be very solid, albeit original to the MH. When we have our required state inspection I will also check with the garage for their opinion. Will also have it weighed with the gear. The kid does not have a house full of things, but surely it will add up so will keep an eye on that.
Mechanically, everything we tested worked as it should. we made good use of the check list posted here so this site has been very helpful in many ways. I'm glad we found you all. I did notice the J channel caulking is ready to be touched up. I went over every inch of this on the roof and found a few spots where it is beginning to separate from the fiberglass. I checked every inch of the inside for signs of water and found nothing. So glad I read about that as well. I am very impressed with the overall condition and cleanliness.
We may have a chance to do a day trip before we set out. If we can get the transaction done mid week we can do this.
I'll be researching road side assistance options and insurance tomorrow.
