Small trucks

Pushing a plow!

You might want to look at the larger trucks.

From personal experience I’ll tell you the Fords are more comfortable. But unless it is a tiny plow you may want a mid size.

Is it snowing in New Hampshire ?

Japanese cars is always good on maintenance and has the best warranties.
In your case they are also stronger (both the 4 cyl and V6).
As for pushing a plow... you don't really need a big pickup. I have seen a Mitsubishi L300 (2,5 liter diesel) over here clear a parking lot without problems. All you need is traction, traction, traction. (4 wheel drive is almost a must).

However, I do notice that most semi - professional snow clearers over here go for the American V8 diesels.

Also another pickup of note: Honda Ridgeline 3.5 litre natural gas powered. It was awarded the Best Pickup 2007/2008 in Norway.
Natural gas is half the price of petrol here and environmental friendly.
Oh, and it comes in a crew cab version too (plenty room for extra car seats for the children).

He did say "small to mid-size," so I'm not sure why you're behaving as though he didn't.

I have no experience with pickup trucks, except riding in them every now and then, so I won't be adding to the discussion. Sorry.

Thanks for the comments so far. I probably should have been a little more clear about the plowing bit. I'm not looking to start a 2nd business, just keep my own driveway (about 100 yards, 90 meters) clear. I hadn't thought of the Ridgeline, Sigurd, but that's definitely worthy of note. Thanks for the suggestion.
