Better than a limited-slip differential ("Positraction" is trademarked) is a locking rear differential. Essentially you flip a switch and the rear differential locks, and you don't get that "one wheel spinning" thing. You can probably get an after-market version put on your truck.
The down side (in addition to the price) is that most of the time you really, really want the rear wheels to be able to rotate at different rates. Consider the relative circumference of two concentric circles. Then imagine the path your rear tires would take if you drove in a circle.
Anyway, also available these days is "Electronic Traction Control." It essentially uses the same technology as ABS to limit the difference in rpm from wheel to wheel. It is, in terms of buying a different vehicle, probably your best bet.
In the mean time, if you get stuck with just one wheel spinning, try putting your parking brake on a little. By adding some drag to the spinning wheel, you might be able to get the other wheel to move a little.
Better yet, move south. I'm about to get up and turn on my AC for a bit.
