excesive slop in the driveline can cause dog bones to snap replacing all bones and cups and out drives with the heavy duty ss parts will help
I've read that the stock parts are better because 1.) they are cheaper and 2.) the stock ones bend, while the SS just break.

The truck only has 1 1/2 gal thru it, I would hope the drive train would last longer than that before a rebuild is necessary.
Mine has nearly two gallons through it and everything IS pretty much lasting, considering the beating it's gotten. Some slight warping, but everything is still good. If one races, then yes, replace it ASAP, but for bashing...run until it breaks and just make a note of parts that look like they may break so that you have a heads up on what parts to get.
