There was an article posted somewhere about the engineers' reasoning behind using the BW 44-44 and the 44-45 transfer cases. The 44-44 doesn't actually lock, it has a clutch for the front wheels which kick on and off with wheel speed changes, and a torque split. The 44-45 which is standard in the Rebel is an actual locker. When you kick on 4wd, you're guaranteed to have power to at least 2 wheels, one front and one rear. It's not as solid as locks in the front and rear differentials, too, but it a bit easier on tires and drivetrain, I imagine.
I rolled my Rebel in 2wd through a lot of snow, some heavy, last winter and only used 4wd a few times. I never had traction issues. I don't have the LSD, either. I've been offroad with it a bit, too. Some mud, sand, and hills. Again, no issues. I'm not doing Jeep trails, just cow pastures and the like. But around here, those aren't all flat and grassy.
