I have a Blazer (1999, not 1998 though). Great engine and transmission. Solid TV. Tow capacity should be about 5K with this vehicle. Consider having a transmission cooler added and remember to tow in "3", not "D". On the flip side, we have had problems, about 1x per year on average, with some non-engeine/tranny component or another (power window motor, heater coil, etc.) . But we use ours as a primary vehicle, so maybe you'd experience less problems there. We have experienced that these rigs really need their regularly scheduled maintenance, otherwise things break. Ask the seller for records on rear end, radiator flush, transmission, etc., scheduled work.
