I have two plow trucks myself, a 73 F250 highboy and 82 K20 soon to have the engine back in it. Both are 4 speed with granny low, soon as the K20 is on the road I'm selling the Highboy. It has a 7' plow that was a home-made job, had the blade custom rolled and welded up all the metal till I had a plow, lol. Since the highboy did not have power steering, I put a power steering unit on it from a 2wd, got a dual coil 12vdc hydraulic valve and just a basic tractor ram to get the right lift, just manual angle. Having to plow 2.5 miles of road all winter to get out, I can tell you right now this set up sucks. Best plow truck needs to be at least a 3/4 ton, have good power steering, be automatic not manual, have a long handle floor shifter with the plow controls mounted off the side so you can move it while jumping from drive to reverse in a jam, use fog lights for back up lights so you can see good behind when it's dark and snowing and have lights up high in the front so they don't get packed with snow when plowing, then the plow should have 4 way control, 8' (v plow really works great, but too expensive for me) and across the top of the plow have a 12" high piece of thick belting bolted on to help keep the snow out of your lights, grill and over the hood onto the windshield when plowing.
I found a good used 8' western fully detachable with the extenda-wings on it for $2,500 with a free K20 attached to it. In my area, most used plows like this go for about $3,500, so couldn't pass it up. Don't have time this year since I did the motor to have a good grunt motor, but next year am swapping out to a TH400 with a Hughes XTM converter like my 86 K20, that tranny set up has taken a ton of abuse and keeps asking for more.
Here is the start of FrankenPlow, hope to have the full set-up done by next winter. Another thing is make sure to reinforce the frame on both sides where the plow mounts bolt on by crossmember. I've cracked the crossmember right at the passenger motor mount area clear through before hitting a hidden rock froze in the ground.
