Tires tires tires. I've had two 4x4 trucks. My first truck and my current truck are RWD. All four of them lived in snowy Rochester, NY. The best snow improvement I've ever made is the proper tires. My current RWD launches the 3500 lb boat at all the freshwater ramps around here without incident. Got this truck super cheap because nobody around here will even consider a RWD full size with a V6. I think it's my favorite of the four...
^^^ this. Lots of folks down here pull boats off the water every day with 2wd. I’ve loaned mine out for the same. Well-siped tires on the ramp do well. Mud terrains favored by some do not. I personally enjoy having 4wd for the rare occasion when it’s needed, but generally find that I rarely *need* it.
