I'm now the owner of a 2003 Suburban K2500 with the 8.1L Vortec mill. I've been considering getting something to replace the 79 Dually with that has more interior room, and with an automatic as I have problems with my left knee. I was looking for Crew Cab trucks, but trucks seem to hold their value quite well, or they need a good amount of work done to them. Just happened to stumble across this one and the price was good. It does have some miles on it at 238K, but runs and drives quite well. I haven't had a chance to tow with it yet, need to get a brake controller installed first.

Plan is to just drive it for now and maybe later do some changes to the tuning. Not sure if I will try it myself or have someone else do it. It seems Black Bear is one the best for tuning this setup, anyone know anything about them? Reviews on the net are positive for them. The Bully Dog tuner also gets good reviews, just not as much gains as Black Bear.
