Review on VIAIR Ultra Duty Onboard System by Lance Harrison

Worked great so far and I was able to get a nice clean install on my 2011 Tundra. Place the compressor under the hood on the passenger side and the air tank under the truck just in front of the gas tank on the driver's side. Install the quick couplers in the rear wheel arches on both sides of the truck. There was enough air line in the kit to make everything work. I had to source some additional parts (on the Revain) including: two quick disconnects, two tees and a plug for one of the tank ports. Installation took a while, but I was meticulous. I called Viair support about the remote relay assembly and they helped me a lot. As a result, I put the relay under the hood, disconnected the tee from the tank to the pressure gauge, which I put in the glove box. I did not use the sensor/switch mounting plate that came with the kit. I installed the switch in one of the empty spots to the right of the steering column. The switch also turns on the backlight of the device. My switch turns on a separate standard SPST relay next to the battery, which then powers the included pushbutton switch. So when the switch is off, I know for sure that everything is off. Overall I'm happy with the set and looking forward to using it.
