Question in my mind is do you go alone or always with someone? I buy lockers first, never had winch. One buddy had a winch and then removed it, because we rairly used it. Another friend has one in the bed of his willy's. Been wheeling lots and use it rairly. The times we have used it another truck would have done the job. Just wanted a little more conrol in the situation at the time. My friends and I never go wheeling by ourselves. I have always tossed the idea around, but never have made the leap and purchased a winch. I believe the lockers were the best investment for my offroading truck, and go hand in hand with the super swampers.
Others are right that they will dig you in deeper, but that is not the lockers fault, that is DRIVERS fault. I run around with guys that run 44's, but very rairly do they get too stuck for another truck to recover with a strap. We run trails, some mud here in the midwest. Usually when we are "stuck" its because we are high centered on something rock tree ect.
This is how my friends and I run, not saying its the only way, just the way we do it. We all run full size truck chassis, some have put ranger/s10/willy's bodies on the full size frames. We do wheel large trucks
