A friend of mine bought a 1984 GMC 3500 military pickup that was used in desert storm. It had around 40 thousand miles on it. He bought it about six years ago and seems to have no problems with it. He did have it repainted. The shop that repainted it tried everything to strip the old camaflage paint off but to no avail, (whatever paint the US uses its quite tough) so the final finish was not as smooth as it should have been. Other than that it seems to be very complete and heavy duty.
