Ok, I gotta put in my 2 cents. I've had a Detroit soft locker in my early Bronco (92" wheelbase) for about 13 years now, had an L.A. Locker (Lock-rites before they were Lock-rites) before that and that thing was horrible (split the carrier in two but, that's a different story) anyway, my Bronco has a manual transmission and it's perfectly civilized on the street in fact, you don't even notice it back there, it's been driven in the snow and over icy roads and it's been perfectly manageable, of course, you shouldn't be driving fast under those conditions anyway. It can feel kinda quirky until you get used to the way it handles but after a brief learning period, it becomes transparent. The only times you'll have problems is when tire (or tyre down under) pressures don't match (making for different effective diameters) or, obiviously, when different diameter rear tires are used. I wouldn't trade it for anything. Oh, and I pull an offroad trailer with no issues.........Hans
