Actually in this location I would...I'm thinking it'd be best to spend the $10k - $13k and buy a used plow truck that's ready to go.
I used to plow snow. I had 18 lots (Wendys, Banks, Used Car Lots, Etc) and there is no such thing as a "Plow truck ready to go." If you buy a brand new truck you have to:
A) Modify electrical system and install dual battery system
B) Upgrade front suspension
C) Upgrade either gearing or shift kits in automatic transmission.
D) Have a heated garage for when the hydraulics freeze up and to make repairs on the truck.
If you buy a used plow truck you have to:
A) Replace batteries and fix the rigged electrical system
B) Repair or replace front suspension and re weld the frame where it has broken
C) Just go ahead and replace the automatic transmission with the heaviest duty one you can find.
D) Keep that heated garage warm! You will need it!
Look, it sounds cool to buy or install a plow on a truck. It's cool too to plow 4" of powder at 30 degrees. What sucks is when you wake up and you have 2 FEET of snow that fell at about 30 degrees and the temps dropped to 2 degrees. That's when you can and will break things like transmissions and crossmembers. Also you never want a manual transmission to plow snow. Too slow in reverse. Knowing what I know about plowing snow and how hard it is on vehicles I would buy a tractor, as mentioned above, with a 3 point hitch and rear blade. It is made for pulling and it won't break easy.
In the years I plowed I think I ended up with only the frame, rear diff, one fender, all wheels, brakes, bottom end of motor and interior as being original to the truck. It was a 1976 3/4 ton short bed Chevy 4X4. I replaced:
Rusted Fenders
Rusted out Cab and Doors
Rusted out Bed
Several transmissions both rebuilt and new
Front Axle
Front Crossmember
Countless of welds to frame
Shocks
Front Leaves
Radiator
Transmission Cooler
Lots of Batteries
Heads
And the list goes on.
I honestly do not think there is anything harder on a vehicle than plowing snow. This includes running it over a cliff. Our Toyota are tough but not that tough. Good luck.
