I don't know if it has been mentioned yet since I didn't read all of the comments but I would highly recommend diesel equipped trucks built before 2003 and no Kalifornia trucks...no emissions!!! You really do not want to deal with an EGR, DPF, Cat, etc. on a diesel. If you are looking at a GM be careful of the early Duramax's; injector problems cost me $1200 to do the job my self (I never trust a stealer monkey to work on my vehicle). I can only speak of my 02 Sierra but after 160K miles the injectors were the only problem...not counting broken parts from 3 deer!!!
