Review on Efficient Control: AIR LIFT 25592 Load Controller II On Board Air Compressor System by Barry Hill

Just does what it's supposed to! My only complaint is that I didn't buy it sooner! I like that I don't have to get out of the truck, look for a portable compressor, connect a plug and then a valve, then wait for the bag to inflate, check the pressure again. All just to do it again for the bag on the other side! Now, sitting comfortably in my chair, I push one button to inflate and another to deflate while looking at the pressure gauge! I can only recommend this to everyone! Installed on my '99 Ford F-350 Lariat CCLB 7.3L Beast without a single problem. The instructions were clear as a bell to me, but might be a little less clear to those who don't have much mechanical aptitude.
