Did you check for power on the main feed wire to the cab?

It is a red #10 wire that goes from the terminal on the right fender across the radiator support and in the harness to the cab through the bulkhead connector.
The wire has a fusible link in it which may have gone bad or there is a bad connection somewhere along the way.

It is also possible for the battery connections to be be making partial connection, (enough to make your meter read but not enough of a connection to power up anything).
