Trying to decide between getting the ARB high output on board compressor that runs for $287 or the VIAIR 400p automatic portable compressor for $247. I will only be filling up tires no lockers or tools. Pros and cons? Would On-Board do anything for me if all I’m doing is filling tires? Arb is 3 cfm and VIAIR is 2.3 at 0 psi.
