I do not have air bags. Needed air for van tires and e-bike tires. Instead of installing a fixed DC air system I bought a 120 volt AC portable compressor. Much less expensive and no installation of air lines or electrical.

I was considering this option (still kind of am) but the major trade off with that option is they take up allot of interior space, mounting the tank under the van frees up allot of room for other gear.

I lucked out. Had an existing empty cabinet below refrigerator where it just fit. Unit is very quiet and appears to be quality.

I did think about separating the compressor from the tank to make it fit but did not need to do that. Permanently mounting both does defeat the advantage of being portable. That would be the same as installing a DC compressor but at lower cost.
