I bought one of the first in 1988 with the then new Cummins Engine. Went 306,000 miles until I sold it. The only problem happend when I let the battery run dry. Shorted out and the alternator went "full field." That wasn't cheap.... But other then that, it worked as it should. I used it off road in the sand washes and rocks, carried my Lance Camper while towing my Jeep, etc. It still lives. I spot it every once in a while around town.
My current is an '06' with 60,000 miles on it. No problems.
I'm sold on them. E
