I don't remember what cam you have, what gears you have, nor what you intend to do with the truck. But those factors, and more, play into the choice of torque converter.
Let's say you have an RV cam and low gearing, like 4.10's. Given the mild cam the engine makes good torque from idle up, so you don't need to rev it up to get into the power band. And the low gears compliment that situation. So, you can go with a torque converter that has a low RPM stall speed, like a stock unit or one made for an RV.
On the other hand, if you have a cam that doesn't bring the power in until 2,000 RPM or higher, or if you have stock gearing of something like 3.50:1 then you need to spin the engine to get things moving. That'll take a torque converter with a higher stall speed.
But, realize that a high stall speed converter means you'll be slipping significantly when the engine isn't above the stall speed. So you will pay a penalty in MPG as well as driveability. The truck won't feel as snappy, and you will be generating a lot more heat in the tranny.
