Jon, my comments were about a Locked front as in welded, not a Lockright. The Lockright opens when not under load so turnins to corners are not forced.
With a welded front when you turn the tires are forced to slip on the ground since the diff will not yield. Driving in snow at road speeds the truck will be very difficult to manage. It will want to remain going straight and you need to make a tire slide to get the rig to steer. This has been written about with clutch type LSDs that are setup with preload. The static preload is enough to make a tire slide during gentle driving on low traction conditions.

Now in low speed driving on dirt, mud or snow the welded front will work. Steering effort will be heavy at times and some of the steering joints will let you know this. Driving on rock the axles do not really get any higher loads on a welded diff than they will on any other locker other than they can get the loads at anytime. If you want to get out a switch hubs in and out, fine. I think I would prefer the idiosyncrasies of auto hubs and select from the transfer case. But that has it's issues too.
