All tires not spinning

[kfrosty]

M932 & M923, I thought these were actual 6 wheel drives. Got in some soft stuff today and disappointingly all 6 wheels weren't pulling. Looked like limited slip? Am I missing something, is there anyway to lock in all 6 wheels? (

Nope they are open differentials unless it's a marine truck which has lockers in the rears.

You can add lockers fairly easy to the rears. PATRACY has a pair in the classifieds at a pretty good price.

How can you tell if it is a Marine truck?

PTO with hyd pump without a winch. Jack a rear wheel off the ground with the brakes released (but the wheels chocked of course) and try ratching the wheel back and forth. It will ratchet free if it's got a locker in it.
