Diesel Bombers - New diesel owner

After growing up with my parents owning an 80's Olds Toronado diesel, watching my buddies's struggle to keep their diesel Chevy's running and seeing my best friend cheer when his F-550 with a 6.0 was swept away by a flood and swearing I would NEVER own one I bought one. 1999 Dodge Cummins, 2WD extended cab dually. It has 300,000 on the od and I had to put a transmission in it immediately but I have been bitten by the diesel bug. I put a used CM SK bed on it, A Ranch Hand Legend front bumper, SB air box, 4" turbo-back straight pipe and am trying to get Smarty S-03 to work then I will install the Airdog II 100gph fuel system. I look forward to learning from everyone. Jteakus
