I'm looking at a gmc flatbed 3500 dmax dually think its an 010? This truck would be for towing equipment, materials w/dump trailer, and plowing residential drives. This is my first year plowing and I keep hearing stick with the single rear wheel truck, but I seem to be towing more and more weight and my with my f350 I'm probably overweight most of the time, it'd b a shame to throw a plow on it when I'll probably be selling it anyway.. be able to tow more and safer too with the flatbed but what about weight in winter without a sander? Was impressed when I tried a dmax recently, the power was all there. Thanks for any tips!
