Being a lake bum in Texas
i found a 2000 gmc ccsb 2500 4x4 with the 454 motor in it. 115,000 miles, leather, loaded nice looking truck. looks like it had a 5th wheel or goosneck setup in the bed (large plate there now coving it up), auto so 4L80E and a 14bff rear axle and dual exhaust to the muffler, looks like 3" with a single outlet after the muffler. dealer has had it for at least a few months, asking 9k for it. my questions are what type of issues to expect with the truck? considering trading in my 95 yukon for it (6.5L 2 door 4x4), also what kinda fuel economy did that era 454 get?
