It’s not very big.But then, what muffler shop is? They have a side-yard to do their work. It wasn’t a straight shot to get the bus in there. They worked on the fix. The problem is that a weld that held the exhaust pipe to the intake manifold had broken. The emergency road service guy put a clamp over it and squeezed the joint together until we could get a more permanent fix. The people that could do the permanent fix looked at the field-fix and decided that was the best approach. With the engine running, they listened with a stethoscope, found a slight exhaust leak, tightened the clamp down a little harder, then put some lock nuts on so it won’t come loose. Again, with the stethoscope, they determined the exhaust to be leak-free, and released us back out into the world. Well, after I paid the bill. Sixty dollars later, we were good to go. Yes; there can be RV repairs that don’t require commas! Good weather. Good company. Good home-cooking. Arizona trip map Tomorrow, we mean to resume our way east.
