I own a VIAIR 400-RV. Will pump up well north of 120psi, reasonably fast for 33" 275/70R18 tires I have on my truck. Nice thing about the compressor is that it will pressurize the hose up to about 150 or 200psi (I can't remember) so it doesn't continuously run. I've been thinking of carrying a little 2.5 or 5 gallon container to supplement it since it has really good airflow for what it is. I use it to air up after driving on the beach (run only 18 or 20psi on the sand so I don't sink in). It also has 60' of coiled hose so you can air up tires on your vehicle and your RV from the truck's battery. It also has to be connected directly to the battery because it will draw close to 40 amps of power.
