Depends on the use of the truck. For an 80-90% on road truck application 
something like an Eaton Tru-Trac or a Torsen is a good choice. It's a 
geared unit so no clutches to wear out and no special lube additives. 
They are quiet and because of the way they operate you can run them in 
both the front and rear diffs without causing binding or steering 
issues. A big bonus is that they operate seamlessly with no driver input 
needed.
They also are not that expensive in that vehicle, somewhere in the 
$500.00 area for the unit.

If on the other hand it spends the majority of life off road AND you can 
deal with their quirks a true locker in the rear with either a geared 
LSD or selectable locker in the front would be the ticket as there would 
be enough slippage to reduce the strain they put on the axles. However 
they will increase tire wear, turning radius and are NOISY as they lock 
and unlock.
