To follow up...
We did not wind up going to Wyoming. We went to Disney World in June and Dollywood in July. It's just as well we cut back the plans. On ther way from Mobile (we did a lot of grandkid swapping on this trip) to Disney we lost the fuel pump and were towed to spend the night in Tallahassee in front of a repair facility. They replaced it the next day (had to drop the fuel tank) and we were on our way. After leaving Dollywood and returning to Mobile, I found a tire separating. I think we were lucky to get to Mobile without a blowout. The spare was road worthy and we were able to get it put on and returned to Stone Mountain without further incident. I'm just glad we weren't on some lonely highway 2500 miles from home when either event occurred.
