It will definatally take a lot of plowing and abuse before you'll tear anything up on your truck. I do plow commercially and My rig is a 2003 chevt 1500 with a meyers 7.5' and wings. In 4 seansons I have only had to replace a front wheelbearing. And with 100,000miles on the clock, it may have needed to be done if I hadn't been plowing for 4 years.
As far as what to get, that is up to you. Tractors with cabs aint cheap, and I know I wouldn't want to be out in the elements on a tractor moving snow, especially with a blower. A truck mount is way cheaper. But the real question is, will a truck suit your needs.
Even tractors do have great traction in the winter. They are light. My
L3400 with loader and rear blade with loaded tires only weighs about 4000lbs. My truck with plow on front and weight in back weighs around 7000-7500lbs. That makes a huge difference. It will out pusk/pull my tractor hands down. As mentioned, a truck will only push so much before it looses traction, but a tractor is the same way. Any my truck will push circles around my tractor.
Someone mentioned that if you have a long flat drive that the blower would really excell. Well, from experience, the truck will excell far past the blower. I do a neighbors drive that is just shy of a half mile long, and prone to drifting. It takes me all of 10 minutes to clear it out. just angle the blade and throw the snow to the side opposite of the prevaling winds, and drifting shouldnt be a problem. I usually plow that drive at ~25mph which is double what a CUT can do wide open, let alone runing a blower.
If you have some pics of your drive would definatally help. I really think you sould talk with some landscapers on your area. Most of them are plow guys in the winter. See what they they think would be the best for your drive.
