snow plow.
Well, I bought my wrecker for that reason. I have notice it slides a little in the snow with junk tires. I have new mill tires that I plan on putting on eventually, but not this winter. I will be putting chains on for this winter. I know some people up here that take chainsaws to their tracker tires at angles to get traction. I might be cutting slits in the center bead with the new tires when I put them on. I put in a coolant block heater and the 5ton cumins 250, and it starts good now. It gets -30 here too. I plan on leaving chains on all winter. I have a 10 foot blade off a state plow. I need to build a mount on the front. The cold means I need diesel additive to keep it from gelling. I don't know about the multifuel but the 250 seems to be able to handle cold as long as you set it up. (And maybe have some starting fluid.) You have to seal the cab. there is a lot of holes in the floor.
My old plow, a 76 ramcharger, with a myer 7 foot blade kept getting lifted up by the snow and ice then getting stuck. It has locker diffs and full chains. I then broke the front outer axles shafts last year while trying to get un-stuck. So I do not think my 36,000 lb wrecker will be lifted up so easily. And the 5 ton axles should not brake as easily. The new blade is also 3 times the weight.
My wrecker has 2 nice winches if I do get stuck. You might look for a truck with a winch as I don't think a pickup with a tow strap will get these trucks out.
I have heard of people putting short box head screws in their tires to help on ice, but that would not do much in snow.
I have not plowed snow yet, but I think it will do good. Ask me in a year whether it works well.
