i run three half tons on residential driveways around Brainerd and Baxter, two F-150s and a Silverado, about 60 driveways between them, so here is what actually happens.
plow: for a SuperCrew with no prep package you want a 7 foot 6 half ton plow, Boss HTX or Fisher HT or the Western HTS, all around 400 to 430 lbs on the front end. do not put an 8 foot V on it, do not put a commercial straight blade on it. the front axle rating on your door sticker is around 3,400 and you will be over it with the blade up and a full tank. an HTX installed at a shop in West Fargo is going to be 6,000 to 6,500 with the mount and wiring.
what breaks, in the order i have replaced them: front hub bearings, both Fords, around 60 to 70k, they take the shock every time the blade drops. then the front springs sag, the nose sits an inch low with the plow up, i put Timbren bump stops in for 240 and it stopped bottoming. then lower control arm bushings. the 10 speed and the 3.5 have never cared. alternator is fine at your 15 pushes, it is the guys running lights and a spreader all night who cook them.
the thing nobody tells you: 600 lbs of sandbags over the rear axle, always, or the back end goes wherever it wants when you push. and do not push the pile onto or across the road, MnDOT and the county ticket for it and it is on you if somebody hits the pile. the state page on that is at dot.state.mn.us, and the 511 road conditions live there too for when you are done with the driveway and want to go somewhere.
