I understand where you're coming from. Based on my experience, seeing how much carnage the guys who worked for me could wreak on pickup truck plows I just am not a fan of relying on them exclusively. Especially considering that with heavy, wet snow you had to have some speed to push the snow far away from the blade and speed equals carnage. The dumps that we started buying with true over the road type plows like Vikings, etc instead of just bigger parking lot plows were far more reliable for roadway use and were much better equipped for casting snow further away from the road. And trust me it was hard convincing the budget wonks to spend $15,000 for a plow setup instead of $6000 back in 2003, but it paid off in the end.
I guess that's why I'm a big fan of an Ag tractor with a heavy duty blade up front, not unlike something suitable for a DOT, coupled with a blower on the back. An Ag tractor can handle a heavy duty blade which will likely be far more reliable. Then when the piles get built up you can cut them back to size with the blower. If you get so much snow that you need a blower to cut banks down you will need an Ag tractor anyway, so why not just stick a blade on it and be ready for anything? That way you aren't maintaing two engines, buying tires for two pieces of equipment, etc. Plus you get the benefit of never having to really push your equipment which sometimes is more necessary with a pickup plow.
And for the record I'm not totally biased against pickups with plows as I have owned one and may end up putting a plow on my new truck. I just think for the OP's needs that a pickup plow is likely not the best choice.
