Another essential gadget I’ve had for quite some time is the VIAIR 450P air compressor, to inflate the tires on our coach.

I already had a tire inflator that plugged into a 110V outlet, which I’ve previously used for truck tires and other tires. But it can’t quite handle the maximum 130 PSI of the coach tires, plus is very noisy. (I inflate the front tires to 120 PSI.)

The VIAIR unit is much quieter, and automatically shuts off when not actively inflating.

Unlike the old one, this one connects to a 12V source like a car battery. I hook it up to the truck’s battery; the truck needs to be running while in use, to avoid draining the battery.

I keep it in the back of our truck, so we’ll be able to use it while driving the truck around if needed.

It comes in a handy bag, and includes two long coiled hoses, so I can leave the compressor by the truck, and reach all of the coach tires:

Here it is in use; it’s easy to inflate by pulling the trigger, and release to read the gauge to check the static pressure:

An essential tool.
