Jeep Hauler
Like a couple others who posted, I use the truck to tow an off-road-only Jeep CJ-7 for wheelin'. I don't like the thought of risking my daily transportation on the trail. The types of wheelin' we do commonly leaves the Jeep broken after a weekend of rockcrawling, etc. It's nice to know at worst, I can winch the Jeep on the trailer and drive my truck home.
The truck does get put into 4WD regularly though. It gets me to work in the snow, goes out in the woods to cut firewood in the winter, pulls cars out of the ditch, and pulls the trailer/camper into backwoods camping spots. Some friends and I are heading for Haspin Acres in IN to wheel this weekend, and just getting the big-azz trailer to where we camp will most likely require locking the hubs...
