Review: Well made, easy install - We bought this to install on our camper as we go riding in our side by sides and it’s nice to have for blowing out the propane lines, add air to tires, blow up toys, and inflatable mattresses. My hubby installed it in a compartment. Works great!
Review: Nissan Frontier small box - Easy to install. Pressure switch & relay protected in one housing! Labelled wires! I mounted this medium duty compressor under the Frontier. I was going to place it in the bed since I have a tonneau cover, but decided against it with what little load capacity I have. I was going to mount the compressor and tank above the drive shaft since it would fit. I am running 32s and a 2.5” leveling kit. The shaft hitting the tank when traveling under load worried me. I decided to remove the spare tire & tire mount. I’ll build a mount on the tonneau cover for when I need to carry a spare. For now, there is the compressor and a tire repair kit in the emergency bag. The On/Off switch & gauge are mounted in the cab near the gear selector. Easy to see when standing outside the Frontier. The lighted gauge is a plus. The air compressor and tank are under the bed, aft of the truck. Away from the differential and the muffler. Air compressor is mounted directly to the bed, while the tank is on a aluminum base plate to keep it level. Wiring for both are out of view. Picture shows the bolt heads that mount the kit. Female coupler is mounted to the tow hitch. It was relocated with push fittings. I had to purchase separately and may change these to compression fittings at a later time. Overall, took me a couple of hours to figure out how where I wanted things mounted & how to install. The Frontier has limited space to work with. Once I made a decision, the install was actually easy. The instructions say not to use it, but I did add teflon to the fittings after reading some reviews that mentioned leaks. The air compressor has no leaks and holds pressure well. Tank takes less than 3 minutes to fill. It provides more than enough air for my needs: filling tires or iSUPs. I may add an train horn later! Air compressor is not too loud. I cannot hear it when underway. I can barely hear it in the cab when the truck is idling. Overall, I am very happy with this purchase.

### ⭐⭐⭐⭐⭐ Awesome product
*by J***S on December 27, 2013*

We bought this to attach to our dually truck, so we would have the option of airing up a vehicle tire if needed. It comes with allot if pieces and parts but once you sit down and look them all over, they are easy to identify. It does take a little while to install completely, but works perfectly in the end. We look forward to using it in an emergency situation
