Not trying to create one those show trucks that go up and down. I want to carry heavy loads and have this thing ride level. Already put new springs with an extra leaf. I thought it would be really cool to put a pair of those big bags that you see on tractor/trailers on my rear axle. (Not just Airides.)There must be a tractor/trailer bone yard somewhere with a bunch of those things laying around. Anyone know how to obtain those things and what sort of compressor would I need to keep them up? Do y'all think this would work or is this just a crazy idea?
