Truck is an 01 dodge 2500. D60/D70. 47RE. Currently on 37's but going to 40's as soon as i re-gear. Planning on 4.88's. My question is about lockers. The truck isn't my DD, but by no means is it offroad only. I drive it on weekends, sometimes to work, etc, but it is my wheeler. My wheeling terrain consists of alot of mud, wash-outs, sand, gullies, etc. Not much for rock in south ms. My first thoughts would be a Loc-right or aussie locker. It's cheap and effective, but i don't know what locker would be right seeing how many miles i put on the truck. Any suggestions would be great. Also do i lock only the front? Only the back? Both? HEEELLLPP!
