My boyfriend has this truck, uses it for his trucking company. It has a utility tool box bed. We recently weighed this truck in at about 12k lbs with all the tools and the box.
The only modification is a larger exhaust system.
Last winter one of his semis ran out of fuel at the bottom of a hill, loaded with gravel pulling double trailers. Then the batteries went dead from trying to start it in 20* weather.
The only way to get it started was to try and pull start it.
We are talking about 25 tons here.
His pick up pull started that semi up that hill. Didn't even burn up the clutch. There is not another pick up on the road that could have pulled that off.
Don't care for the seats, but it could just be that the previous owner weighed alot because the drivers side is worse than the passengers.
Door panel window switches tend to go out.
