Not just any old average Christmas tree, but the 60 ft-er at Disneyland with their July 4th fireworks show. It was easier to count the number of items NOT lit. The mechanic was even trying to tell me that the computer in my truck was one for a 3.0L V6 and not the 2.3L 4 banger I had.

Will this help, probably not. Will it add to your confusion about what it could be, probably. Sorry. But I can tell you that I drove the thing into the ground. When the motor finally froze up at 313,000 miles, I gave it a nice memorial service and sold it for $350 to a guy who turned it into a pre-runner.
Yep, immediately after.

I put the truck on a vacuum gauge, and the vacuum readings were all within healthy spec. However I only tested the vacuum without a load. Under load is where my problem is, especially when I'm physically holding the load, like when I have the brakes on. The truck is not throwing any codes at all that I am aware of, at least none that will trip the CEL or show up on Autozone's cheap scanners.

Ok, I just read all 5 pages and after reading your last post Im gonna give you another educated guess as to whats wrong.

You mention your problem happening while its under a load and you have your foot on the brake.
To me it sounds like it could possibly be your power brake booster?
A quik check would be to remove the vaccum line going to it and plug it with a bolt temporarily to see if you still have a problem.

Hope this helps?
