I am going through this now. The portion of Jersey I am from (in the mountains) gets significant snowfall and its time to prepare.
Re Snowsport: Problem one is that a front hitch for the 2500 is not available.
Problem 2 was: if you send away for their literature, you get a DVD of the movies on the web site; What I saw from the more detailed version on DVD that I didn't like was the assembly that holds the plow deflecting toward the hood/bumper as it hit the snow. Makes sense as essentially the whole thing cantilevers off one point (the hitch) on the front of the truck.
I can see myself slipping into a really big drift and denting my hood.
I hear they do work though and maybe I am being overly cautious.
For the same money, there is an alternative: http://www.snowbear.com
It is a "homeowner" class plow but looks heavy enough.? It comes with a winch to raise and lower it but angling is done manually.
Their plows are available at Lowes for $1150 (small 220lbs) and $1500 (large 320lbs).
BTW - By comparison, a Fisher Dealer quoted me $3500 for a "real" plow and the installation involved cutting the cladding (shudder.)
For more info, go to http://www.plowsite.com and look under the non-commercial section - there is a lot of discussion of both the Snowbear and Snowsport products.
From what I have seen, there are several "professional" firms that use them.? My UPS guy, who used to be a landscaper also used them and recommended them without reservation.
Word of caution: There are issues with driving around with these on.
First is cooling: it blocks the radiator and may be an issue at highway speeds (on the 2500 it would block the extra vent with the trannie cooler in it above the plate.)
Other is police issues: may block plate, may block lights and turn signals.
If you have the plow prep package, the cooling will not be an issue as you already have a different fan to accommodate the airflow restriction.
I plan on getting around both by using the dollies it comes with and putting in on, doing the few driveways I need to do and then dropping it off before heading to work.
Note that for some years, the plow prep package was not available with a sunroof . . . not sure what that means, I'll let you know if the roof bends and the sunroof will not close after I hit that first big snow drift.
