i know this might not be the right forum, but i want your guys input. My truck in sig has 120,xxx runs good for what it is. I've been throwing around the idea of getting a diesel for the past year or so, i finally found one. its a 2004 4x4, lb7, one owner, almost identical truck to mine, slt, black leather interior, full power, loaded. it has 112,xxx miles on it, its black also. the only thing im leary of, i know an older couple owned the truck since new, had all service records kept at the place it was bought at, they have a 5th wheel ball type in the bed and pulled a big camper with it. its obvisouly had an edge programmer on it which isnt that big of deal because they are fairly safe. everything is tight, under hood is clean tranny is clean, fluids look good. only flaws i seen were drivers seat is wore on the edge, and a cracked windshield at the bottom. the buttons on the steering wheel control and the radio arent even worn, and doesnt look like the arm rests have even been down. should i trade my gas burner for the diesel with boot or keep mine and do a 6.0 swap in the near future. i know its right around the milage where the injectors start to crap out, and i dont know if they've been replace. btw they want 22,900 for the truck. is it worth that?

thanks for your input,

steve
