Im glad this thread has started so much discussion on compressor solutions for our vans, its definitely a rabbit hole of options out there. I was asking my mechanic what he uses and he recommended a napa maxi trac portable compressor, which for the price could be pretty good albeit a non mounted option.

I wish it wasn't online only, but maybe I can return at a local napa store if I did order it and it doesn't make the cut.
I found this video on youtube where a guy compares this to a twin air ARB compressor and the napa portable is faster at fill time compared to the ARB:
I might look into this as an option a little more, could work for me since I'm not going to be needing to inflate too too often maybe just a dozen or so times a year with my 33" tires. Real question is can it get these tires up to 50 to 60 psi which is what I typically run when on the pavement.
