The manual for my Horizon 1500 says 2 AWG (25mm^2) is adequate for a
60' run.

You have to calculate both sides of the circuit. 40' from the battery
to the winch and 40' from the winch back to the battery. A 80' run of
wire. ...

Fair enough. For a 90' run the manual says 1 AWG and for a 120' run
it says 1/0.
