Portable Air Compressor for Truck and RV tires

Aside from PSI look at CFM (cubic feet/minute). A high PSI w/low CFM will leave you standing for an hour waiting to pump up a tire. I haul a Craftsman with me that probably weighs 20 lbs. or so. It only runs off of AC so you must also have a generator. The small black lunchbox size DC compressors are handy but you'll be at least a year older by the time your tire is inflated.
