Land rovers do quite well with 3 open diffs F/R/Center and electronic traction control... as long as the electronics are working and your brakes are not overheating. These systems have been around for a while and seem to hold up.
Learn to use your e-brake, especially with LSDs. When one wheel has zero traction, an LSD will do little for you. A touch of e-brake will send some torque to the wheel with traction--works even with open diffs.
