I carry a Torque wrench, an extra long 1/2" drive socket breaker bar, sockets for every size bolt head of substance on the RV, a battery powered 1/2 drive drill with two batteries, , an extra hydraulic jack in addition to the screw jack in the truck, leveling blocks, tire blocks, a 10 gallon air tank @ 120 PSI for tire touch up and air bag touch up, flash lights, electronic tire gauge and road warning signs in case I'm disabled along side the road. When we had our tire failure in the middle of nowhere we changed the flat ourselves. Had forgotten to check the air pressure in the RV's spare Tire recently so it was low. The 10 gallon air tank with pressure of 120 PSI brought the spare tire right up to snuff. You do what you have to do when you are in the middle of nowhere. Surely we are capable of changing a flat tire. It's not that big a deal folks unless there is no place to get off the road and away from traffic a bit. Apparently all the 18 wheelers, automobiles and highway Patrolmen that went by were not very concerned about us. Nobody stopped to see if we needed help. We didn't but.... kind of unusual
