Oh yeah, it also already has rear air bags on it. It doesn't have a compressor, so you fill the air tank with an air source at home right now, then can fill/dump the bags with a little control valve/guage. I think I'm going to add a compressor at some point in the future.
I'm also considering putting on CNG as a cost saving method. There is a public filling station a few blocks from where I work. I was thinking I'd put the fuel tank in a tool box in the bed.
