I have the H.F., it's good, but you should have a holding tank for best case (with the 12v. pump.)
The High pressure tank is the best way to go period, but pricey. I have used the 5# tanks in the A/C and refrigeration business for 30 years, thrown them around, even dropped one of them accidentally, off a 2 story bldg, safe as can be. I have 3 with me now, and with my tire troubles, I have exhausted only one this trip.
I have mine piped into my truck air system, valved off, use the H.F.pump 90% of the time, air horn, air bags in hitch.
I have a compound gage on the 5# tank, set at 120 supply.
