Which is better for off-road, limited slip or locking? Does anyone know which the Toyota T-100 4x4 has? If it is just plain then doesn't that realy make it a two wheel drive in the mud or sand(one in front and one in back?)Is there an aftermarket locker or limited slip for this truck?

I personally prefer the way the limited slip works better. But I'm sure you will find differing opinions on that.
I just visited the Toyota web site, and couldn't find any mention about what axle type the T100 has. They don't list options for that either (other than axle ratio).
You're right about the regular axle on a 4X4. It is effectively only 2 wheels driving (one front, one rear).
I have friends that have SR5 trucks, they came with the regular axle. One of them installed an aftermarket locker differential, and that made a world of difference on where he could go off road. I don't know if there are aftermarket kits for the T100. You'll have to ask around I guess.

I am still not quite straight on this. I am going to order a new model '99 Chevy or GMC Full Size 2x4 pidkup with a tow package. There is no limited slip differential offered ... only a locking differential ($270 option). I will only tow a boat a couple times a year.
Should I get the locking diff?
Will it adversely affect gas mileage, performance, or handling?

That's the limited slip, #1. The manufacturers don't offer actual lockers. For true lockers, you need to go aftermarket. Add in the fact that each one has a different name for limited slip, and it's easy to see why a lot of folks get confused on this.

I would say that limited slip will not affect gas mileage (maybe in some minute theoretical calculation, but not in reality)
Performance will be improved if your vehicle has enough power to spin a single wheel when accelerating (laying rubber). When both wheels put the power to the ground, you can launch quicker without spinning the single wheel.
I would think handling should be more predictable as you come out hard (heavy gas) from a low speed sharp turn, because the shift of the vehicle weight in either direction will have the same result. In my F150, if I give it too much gas making a low speed sharp right hand turn, by back wheel (passenger side) wheel break loose and spin like crazy because most of the vehicle's weight is shifting to the front left. On the other hand, if I do the same thing making a sharp left, I can come out of the bend quicker because the right side of the truck is receiving the weight shift which puts more downforce on the right rear tire. My Cobra on the other hand (with posi-traction) lets me accelerate out of left and right turns the same.

I assume then that there is no appreciable vehicle weight increase when adding a locking differential.

Your assumption is correct. I can't recall all the pieces in each of the rear-ends, but I know there are only a few more parts. No more than a pound I bet.
