I use the MV50 with a 2 gallon air tank, pressure switch relay, yadda yadda yadda.
I can't wait to move to CO2. With it all mounted inside, it overheats easily and I have to let it cool down between front and rear tires. The 120lbs in the 2gal tank shaves off about 3 minutes worth of fill-up, I guess, but takes five minutes to bring the tank to 120lbs from 0, or 2 minutes from 80.
Edit: read the above as saying: if you're going to go with the MF1050/MV50, don't bother with running an external tank and dealing with all of that hassle unless you intend to run air tools (which I thought I might... one day.). You'll just spend a bunch of money and end up being frustrated.
Get it, it works, be patient, and keep it outside of the vehicle when running it.
