Well, I got success! Here's the story: After I replaced the fuse, I noticed that the cargo light started working. Sure enough, the fuse panel says it should. But, the dome light did not. Turns out my headlight **** had been turned full clockwise the whole time and I didn't know it. So, I got a multimeter and checked the circuit at the dome light. I got positive readings (of VERY different levels) from each side. But, I was fairly certain that I had power to the light. So, I went by the junkyard to see if I could find any other lights. When I finally found an 87-91 F-150 that still had the dome light in it, I noticed one thing right away. There was a third screw that I didn't have. Guess what it does?? Yep, it screws into the sheet metal and grounds the circuit (Thanks to Sean for reminding me about that important need in electrics). I took that screw and as soon as I put it in my third hole (so to speak) the bulb lit right up!

Thanks to all you guys for walking me through all the components!
