Go to a 4 wheel drive store. They have real small 12 volt compressors with tank used to air back up after going off road. We put air lockers on my sons jeep and the compressor is about 12" long 6" wide and 8" tall that comes with air lockers. We got the air hose and air chuck which plugs into compressor. 4 wheel parts store have kit that uses air conditioner compressor and comes with a dash switch to engage or disconnect the clutch , you use as air pump. We have a large compressor in trailer to air up truck tires and trailer tires after day on sand dunes. To slow so we use pressure tank from welding store, very fast air up, 6 tires on trailer and 4 tires on truck almost as fast as you can walk around. 4 wheel stores now have a tank with handle and coil air hose all made up that you can buy now ready to go. Just have fill up as needed at welding store. Sorry for the rant , I just got carried away. If you have room the air conditioning compressor would probably be the slickest.
