update:
I pulled the gauge and the sender out. I wired directly to the battery (positive and negative). Sometimes when I moved the sender, I got the gauge to move. I then put another gauge in place of the in1 itial gauge and had the exact same results. SO.....I went back to rechecking from the beginning. The sender was pushing out 21 OHMS sometimes, but not all the time. Most of the time it was not sending out anything. The highest I could get either gauge to move was from "E" to "1/2 tank".
Result of testing: it was not the gauge, it was the sender despite originally getting the correct 0-30 OHMS. Time to purchase a new sender and have it here ASAP so that I can drive my truck with confidence that I am not going to run out of gas.
Next test: ensuring that the new sender works with the gauges and then retest again once it is actually in the truck on the "every day" wiring.
Thanks guys!
