I think before you buy a 1 ton, look at two sized trucks.
The "15,000" GVWs GM 3500 HD's and Ford F 450. These trucks with enough weight added and chains, it will plow fine. They are also a better choice for work trucks because of their higher payload, if you want to carry a v-box with a full load, these trucks are a better platform.
The other size:
The Ford F 650 and International 4700, trucks with GVWs in the area of 26,000 just under CDL requirements.
Now these trucks are true mid sized trucks, that are heavy duty. They have a high curb weight, and when you add the body, and possibly the 5 yard sander, you will be able to plow any lot with ease.
Again these trucks are larger and heavier, and have high maintmance cost. However they are very economicly priced work trucks. They have a much greater work truck capability.
Price wise you will be suprised at the cost of a Ford F 650. You can find F 650s with the cat 3126 B engine, and 6 or 7 speed trans, 10 or 12' frame lenght, xl package, for under 34K. Now upfitting will cost a little more than a 1 ton sized truck, however you will have a heavy duty long lasting work truck.
Do youself a favor, look at all the options before ya buy. The last thing you want is to buy something and find out a year later it isn't what you really want.
So price and look at 4X4 1-tons, 15,000 and 18,000 GVW 1 ton sized trucks, and look at true medium duty work trucks with the 26000 GVW range.
