In reality, it might be best to keep the tank full and run the vehicle every so often so that the internals of the fuel system stay "wet with fuel".
The "full tank" leaves less inner surface area of the tank surface to "sweat" or make condensation with temperature changes. Keeping the rest of the system "wet" can similarly minimize moisture accumulation when the vehicle is not in use. Main issue here can be the guts of the fuel pump, especially if it's a "vane" pump.
Draining the tank might help that area, but if the rest of the system dries out, then the internals can accumulate "rust" and that can cause many more problems and equipment failures.
A fuel stabilizer might help with "freshness" (probably from lack of octane loss via evaporation, but if things don't work out and it stays in there too long (enough so that evaporation leaves only the stabilizer "coating", then THAT can cause issues too. In the AACA forum post on that issue, "red" stabilizer was the offending thing in trying to get it out of a carburetor for a rebuilding situation.
You might need to find an alcohol-fuel car drag or boat racer with a real alcohol fuel system and see what that racer does in the off-season.
