I have the monster Extreme Air Outback Magnum - bought it thinking that bigger is better! And dont get me wrong, it's great.... But it takes up a ton of room and is very heavy.
Coupled with about 10 gallons of air tank capacity at 150psi it's almost like having a small shop compressor with you all the time. It does tires super fast but honestly I've used the blow gun 5x more often than the tire inflator while on the trail. Just yesterday I had a leaky bead from some gravel pinched in there and was able to deflate the tire, push the bead back with a pry bar, and blow out all the junk with the blow gun, and re-inflate in about 10 minutes.
So I'm on the fence... if I were to do it again I may try a smaller compressor just for the ease of packaging and installation. But this one sure is nice.
