The Coachmen must be like Sunseeker, where they don't install a winterizing valve. It's just dumb IMO. And putting antifreeze into the FW tank is dumb too.
If you have a water filter cartridge, remove it, and reinstall the empty filter canister. Then use a hand pump gizmo which connects to your city water hookup, and draws from an antifreeze jug. These are available at most RV dealers, or online. You will fill the filter cartridge, which is a waste, but nothing like putting it into your FW tank. Some people put a sealed water or soda bottle into the filter canister to reduce the volume.
Good generic instructions
