our son's work truck is a state vehicle. the last one was a dodge hemi. at about 125K miles he got a new ford, the old dodge went to rangers at parks.
he did lots of towing with it, towing a 10,000 lb v nose filled with motorcycles quads and side by sides around the state.
His co worker with the same truck is getting a replacement. I believe his co workers has around 150K miles on it. he also tows the same trailer around the state as well.
Neither has had any engine, transmission or drivetrain problems. Few other problems with some other functions, but nothing major.
