Good work truck. recently the hood was cut as pictured to get it open when the latch broke. Last spring it had a new water pump and was flushed well. It leaks a little transmission fluid and it burns and leaks a little oil. Exhaust has a leak near rear wheels. I put one or two new tie rods in January and i put a new idler arm and pitman arm burt did not get it alighned so one tire wore flat. the other tires, ne one the front is pretty good and the two on the back are very good. I also replaced the carrier bearing in the drive shaft and put on 4 new shocks in January. I used it to pull a goose neck trailer with about 10 tons on it. I took it to Hastings this year several times loaded which is about 3 hours from home. Tires are Hankook LT265/75R16 tires and one spare in rear. Battery is a good interstate and extra battery in box.. I do not know anything about. Heater works AC does not. dual tanks but passsenger has never been hooked up since i owned it. Goose neck ball and all three sized on bumper.Rims came from a 2006 3/4 ton GMC truck. so they are newer.Hear it start and run on this video made auction start dayhttps://youtu.be/FJiNMif4LjY
