Every seemingly non-biased review/test I have seen, that was well implemented, says no. Your mileage may vary (buh-dum-tss).

Simple to Google. Same as gas trucks. No....

Mine will actually decrease range, as it weighs a lot, ~125 pounds.

I think I did gain a tiny amount of range, with a hard Hummer spare wheel coven on my spare wheel underneath the truck. I kept detailed notes for a few days after I plopped that spare cover on... it equated to a savings of .1 kWh overall. Nothing to sneeze at when stretched over the projected life of this truck, and it justified the spare wheel cover's price in my eyes.

I did have to drill drain holes in its periphery after I had to use the spare wheel after weeks of rain... there was a gallon+ of accumulated water in there. Now with the 11 drain holes around its perimeter flange, there is zero water accumulation.

No.

I do wish Ford had made the underbody more aerodynamic.

The best tonneau cover is actually a topper. The wind tunnel and CFD tells the truth:
