best wishes in your locker adventure .. i probably run the heaviest rig( 88 suburban 60front w/locker big block 5spd tranny 14 rear locked ,8500 empty w/ trailer 14500 total weight ) i run a Detroit locker, stock axles,I've run 38-44 in tires 14-24 inches wide i also tow w/ this rig..........YES IT IS A DAILY DRIVER. I've taken this truck from New Mexico to Canada,north Carolina to Utah , I'm military I've worked the hell out of this rig and it took 15yrs to kill the locker,and axle I'm pretty sure you don't need to stress toooo much on your decision..MECHANICAL and carry your spider gears......... K.I.S.S. Keep It Simple Seriously
