I used to drive this truck hard every day as a ranch truck. It has been the best performing 1/2 ton 4X4 I have ever owned. There is currently 340000 miles on the original 350 engine, and it still passes CA smog tests with flying colors. The auto tranny has to be rebuilt every 100000mi. Have had electrical problems with lights and the heater controls. Other than that this is a nice truck for the year and money.
Independant front suspension. Factory skid plates that protect everything (You should look under some of the brand new 4X4 trucks out there.).
Better gas mileage. Stronger rear springs. Stronger bushings on the front end.
It was a lease back, had 116000km on it. At 240000km rebuilt auto tranny. It has 350000km on it now and I have to get the tranny fix. It has been to Oregon. I drove it to the mountains sledding for ten years and never missed a beat. Now I pull my fishing boat and take it hunting every year. Great truck!
Solid 4X4 with the right tires
There is a antifreeze line that runs to the rear of the intake manifold. The fitting that screws into the intake gets corroded after awhile and starts leaking. When you remove this fitting it breaks off then the fun starts!

Bought this truck about two years ago and have not had a problem since. Dropped a brand new engine and transmission in and it runs perfect. I have flowmaster mufflers coming off of edelbrock headers get 24 miles to the gallon on the highway with a 350 v8 which is unheard of. Runs perfect and no imperfections or complaints at all.
All the crazy cool stuff I put in it, but it just runs perfect, not a shake or rattle on the whole truck
