Okay I've looked thru a lot of threads and can't seem to find exactly what I'm looking for. I have an 08 CM 2wd that is at stock height, I'd like to lower the rear a little to make the truck level, however I also have a travel trailer. So I'd still want to raise the truck back to tow my trailer. I already have a LDH, which rides level when the trailer is attached. I figured air bags would be my best option, any suggestions on what I should get or do?
