I still haven't seen a storm yet though that can stop my F350 diesel and 9' plow.
I pretty much agree with this statement.... I had 2 storms stop my old 86 Chevy plow truck, but we are talking 4' of snow in each storm ;-) and really it was more of a 'slow down' than stop.
I now plow with a 95 Suburban Diesel... which does a decent job. MUCH Better after I added limited slip to the rear axle.
Probably my favorite plow truck was my ex military Chevy Blazer (also diesel). It has limited slip in the rear as well, but even though its shorter, it weighs almost as much as the suburban! Plus the 'shorter' really helps to maneuver. Especially in short driveways.
Honestly, the plow vehicle I have always wanted, is pretty much what you already use! I always wanted a decent jeep with a plow on it. I would think for doing subdivision driveways it would work awesome. Especially if you had a 'back blade' edge on the plow.
From what you describe, it doesnt sound like you get enough snow to really worry about long term snow placement either. But for that, a decent CUT with loader would be a nice addition to allow you to move banks if needed at a later time in the winter. I know mine has certainly assisted this winter (although it wasnt NEEDED, just desired).
Curious, how long is the average driveway you would be plowing?
