Aw man, I wish I would have seen this thread sooner back when I was at our farm. We have a standalone air set up in the Silverado 2500HD we just bought, along with airbags in the back. Shitty, I cant for the life of me remember the brand. If you still haven't found what you're looking for let me know.
I'll call my dad and get him to check on what it is exactly.
It works extremely well, it just bolts right in. The compressor works quite well for what it does, it doesn't take long at all to fill the bags to whatever PSI we want.
