Gone, but not forgotten...
A stuck float on the fuel level sender? Can you get to the wiring harness to do some electrical tests?

I have a full load in the bed....so getting to the sending unit would be a last resort ( thanks GM for not putting a plate in the bed over the fuel tank sending unit)..

Not overly difficult to drop the tank. Lines, wiring, filler neck screws, ground strap, then 2 bolts.

Before you get waist deep into this, be sure it is the sender, and not the gage or communication issue. Use a scanner to read the fuel % level. If it matches the gage, then it's likely the sender. If it doesn't, then it's more likely a gage (IPC) or harness issue.
