Changing air pressure

The ARB deflator is super fast and precise. You can deflate too any pressure as it has an integral gauge. The Staun and similar work well is you are only ever going to deflate to a specific pressure. For me, the ARB works better. As I can deflate to daily driving pressure when the camper is off and still deflate to off-road pressure if needed quickly with the same tool. I used to use the chuck with the hose attached but this is orders of magnitude faster as it removes the center of the valve but keeps it captive so you don't lose it.

Staun deflaters are another brand and they have two or three different ranges to suit different classes of vehicles.

This is what I like about this forum. There's always someone that can answer even what seems like a stupid question. I considered deleting my question thinking how dumb it was but then I learned there was the Smitty tire deflators. Never knew they existed. Awesome.

Might want to look into using what off roaders use to lower the pressure in their tires.

Might want to look into these. Smitty tire deflators

I don't have an easy way but if I'm letting out more than a few lbs I disconnect the chuck from the air hose and air it down with that.
