I decided that I have plenty of cars with computers and whiz-bang cool stuff in them...I wanted to keep my truck as simple as possible. This helped a lot when I was driving and I would have to replace the alternator or voltage regulator or a power steering belt....these things were fixable on the side of the road with simple tools. So, as much as I liked the AccuAir ads (I watched the GMC one at least 3x a day), I was going to use switches, and set it up in a way that would not have side-to-side transference of air when in turns, and would be quick enough for up and down action. I was not trying to hop my truck (even though it can do that). I decided on 3/8 lines and valves, 2 ViAir Compressors with a 5 gallon tank and Firestone bags.
I did the aluminum tank instead of chrome
