I don't have a ScanGauge and an ABA test over several weeks with full

I would keep the flat rims, and add a cover to the bed.

Yes, in fact, I'm making a tonneau cover as we speak. Just waiting for
the spar urethane to dry before moving on. Other plans are lowering
2 or 3 inches, electric fan (stock is a mechanical clutch fan which always
provides some drag on the engine), and partial grill block. Hoping to get
above 30 mpg with all that.
