No issues. I have the portable because I have 3 offroad rigs + offroad trailer, so I never know which vehicle we're taking until right before the trip. I only use the co2 tank in my jeep that has a rollbar bracket mount. The viair400p (original compressor) was just too slow airing truck and trailer tires back up.
What does a $750 Power Tank do that a 20lb Co2 tank & regulator for $200 can't do?
That 20lb Co2 tank & regulator can't show up at your door in a Powertank box, with all the Powertank goodies and the Powertank decal on the side???
Nothing. I think I have $150 into my 10lb tank setup and that includes the mounting bracket to my rollbar. I bought everything new besides the tank.
Thats not apples to apples. I’ll show you the difference between those 2 compressors though.
I did this on my Jeep back in the day, double tube 3" bumper front & rear. heli welded end caps and fitted air fill valves, could fill both with 120-150 psi, and use to refill after wheeling, worked well, and fast, but kept a portable compressor as a backup.Most of my wheeling has been in the mud of the midwest, not a lot of need for airing down and rock crawling.
So, this might be a really dumb question, but why not integrate a tank with your front or rear bumper. You could run a fill line to it from whatever compressor you wish to run and you would have both high pressure and indefinite volume? If this is a good idea, take it! If it's a bad idea, I promised nothing
I have used both...Powertank is my preference...I run with (2) 10# Tanks...it's quick and it's simple. If I'm just going out for a couple days...I usually only take (1) tank. The onboard works great however it's just slow.
A couple of KoH drivers said they aired down to 30. Not much, but still aired down. Barely.
