Starting (SLI) batteries have much thinner plates, and many more of them, than a deep cycle battery. They’re capable of delivering enormous amounts of current, much more than any comparable size deep cycle battery, but they’ll live a short life (burn out) if you try to pull current from them for extended periods, such as winching. Most modern SLI batteries use a sponge or sintered type plate, for even more surface area in a smaller unit volume, but this makes them even more vulnerable to failure when deep cycled. They are really designed to operate at continuous 95% - 100% charge, and will usually die after just a few dozen deep cycles.
Deep cycle batteries have far fewer, but much heavier solid lead plates. They are designed to take hundreds or thousands excursions into deep-cycle (below 50% charge) territory. Because of the solid lead plates, they have less surface area, and thus lower starting current (cranking amps), but they can run longer at winch capacity (150 amps) without damage or failure.
I am not sure what type of battery would be used on your truck with the special plowing rig, they may be deep cycle, I suppose. Normal single-battery gasser pickups always have SLI batteries.
I’ll be interested to see how you mount your winch. I mounted mine up high, on a tripod stand above the rail, so I could pull logs up the gate and right up to the front of the trailer. A smarter route is the toggle that a few here have mounted to the rails of the trailer, which physically lift and place the log on the trailer, I may go that route in the future, but what I have works pretty darn well.
