yea, I've got ARB OBA and I also carry a Q-89 dual cyl compressor when I take the trailer
I've gotta add a note on the Stauns use---you can set them for whatever pressure you NORMALLY want the tires set at, mine is 18 psi--NOW
When I've dropped the pressure (snow/sand) down to 8/10 psi, I don't mess with the setting--just pull each (PIN) up for about 3 sec per lb psi, or 30 seconds to drop down to 8 psi/per tire
Don't be letting air out of them tires unless you've got a compressor, if you've got them down below 18/20 psi, they're not designed or safe to drive on the pavement, if you want to just go to the nearest gas station--unless it's SUPER close !!
