I had one of these in a 4Runner I had many years ago and liked it so much that I bought another one for my JK. In the 4Runner I separated the tank from the compressor and shoehorned them into the massive empty space in the rear fender above the wheelwell, but for my JK I've kept it together and I just toss it in the rear footwell when I'm loading up for a trip. I wired up a quick-connect to my under-rear-seat auxiliary battery. It's too big to permanently mount anywhere on the Jeep - it just takes up too much valuable space. It's a very fast compressor and has been perfectly reliable. The small pressure tank is a real nice addition. I can usually fill the 35" tires on 2 vehicles in the amount of time the common Smittybilt "high flow" can fill a single set of 33's. For the price, it just can't be beat!
Thanks for the review!
