Big Rig Breakdown

We had a flat tire on the RV today. The air valve for one of the rear tires broke and, of course, the tire went flat. 
Replacing the valve required removing the tire, removing the tire required lifting the rear axle of the RV, lifting the rear axle of the RV required a jack capable of lifting something that heavy, getting a jack that could lift the axle required a call to roadside assistance, and roadside assistance required a hundred dollars to send someone.
     But the guy was pleasant and knowledgeable and had us back on the road in just under 2 hours.  And that was after we'd spent the morning trying to solve the problem ourselves.
