If we had to break down this was the place. I really like this CG, Johnson Creek RV Resort. It's a bit expensive but a great location beside a pecan grove in the Texas hill country. We stayed put without any wheels and walked aroung the CG and immediate vicinity The Ford dealer called early in the afternoon and said the engine was repaired (replaced two hose clamps on the turbo hose and reprogrammed the computer) and was going to look at the low speed towing vibration broblem. They picked us up before 5pm and took us back to the dealership so we could get back on the road. They felt the vibration was due to the drive shafts carrier bearing bracket being too long. They didn't have one so I'll look into this at a later time as they thought this isn't causing any damage. I'm still considering rear air bags to level the truck when towing.
