Yeah, I sure wouldn't try this on a bus. Most plows that I see around here are mounted on 3/4 ton trucks. The dual rear wheels on the back hurt too. It distributes the weight too much. Then you don't get enough traction on the rear wheels. If you've ever seen a dually stuck in the mud, you'd know what I'm talking about. I just don't think it would be practical on a skoolie. MAYBE a bus built on a van chassis with a diesel and a single rear wheel axle. Even then, I don't think it would work that good.
don't get me wrong, i think a skoolie would make an excellent "plow truck" when it comes to pushing snow. Although not so good when it comes to maneuverability. Not much different than this truck: (minus the 5 tons of salt he can put in the bed)
on a conventional bus, or preferably shorter i think a skoolie would push far more snow than any conventional 4x4 1 ton pickup truck. I'll gladly hook a strap from my bumper to any 1 ton 4x4 and play tug-of-war with them on snow gravel or dry pavement.
one more negative thing about a plow bus. Getting stuck! Though it probably wouldn't happen often, It's never good to get stuck when you're the biggest thing around. Be careful.
i think you should put the plow on and make a youtube video plowing through 12 inches of fresh snow!
