Viair 400P-RV Automatic Portable Compressor Kit

Our Viair 40047 400P-RV Automatic Portable Compressor Kit connects directly to the batteries instead of the cigarette lighter.

It comes with 60 feet of hose – enough to reach the entire rig.

When we had a blowout in the Mojave Desert we learned that not all AAA responders have a compressor onboard. Fortunately, we had just purchased this equipment.

So easy to check the tire pressure and it takes just seconds to use.

Our compressor has also come in handy for fellow travelers in distress.

We think this is vital equipment.

The handy carry case is included.
