I have been driving a 1988 Ford F250 7.3L diesel for a number of years and it is time to move up a bit. I am looking at maybe buying a 2006 GMC Sierra 6.0L V8 but with 189,000 miles on it but in excellent condition with tow package and canopy. I am retired so looking in an affordable price range, hence, the 2000 model years under consideration. I plan to carry an 8 foot camper at most pulling a 22 foot boat. So, do these trucks last a long time such that I wouldn't expect a bunch of problems with it. Carfax shows it has had regular maintenance since it was new. An exhaust manifold gasket and a water pump was replaced a year or two ago.
