All d2's 1999-2004 could possibly suffer head gasket failure. There's several other things to watch out for with them. You have the three amigo lights. "Abs, tc, and hdc" in which only a special scan tool will give the codes for. Also the front drive shaft, the a.c. lines drip right onto it resulting in driveshaft failure due to non-greasable u-joints...causing them to snap and sending your driveshaft into the transmission. Remedy "Tom woods drive shaft" oh and rust.
None the less, they are tanks and I would love to own another one! Awesome thing about a 2000 is it has the tcase with a center diff lock...just no way to engage it in the cab, lucky 8 makes a tcase shifter to engage it...or you can find a wrecked 2004 or D1 and swap them out. In a day you can a cdl with a little modding and around $500 or less.
