bowhuntercoop...I got that same truck, a 2003 with 111,000 on it, 305hp HO and always garaged. Pretty much stock with the factory tube step boards except for a Road Armor front bumper and 35"x315 tires on the factory rims. Has a Diamondback bed cover. These are awesome trucks and I get compliments everywhere I go with it. Thinking about putting the factory front bumper on it though...but as-is it looks as mean as all get-out. Those 5.9 diesels can easily be built to take 700hp without getting into the block. However, you will also need a built tranny.
