You should get some fogging oil into the cylinders to protect against rust. You also want to take care that the raw water feed doesn't freeze up and crack anything.
The problem with fogging oil in a diesel is it will run, and may well run away on it. Diesel fuel itself is a lube. Make sure the cooling system is winterized, cover the exhaust and just let her sleep a few months. When you go to wake her up, hold the shut off in no fuel position while cranking for 15-30 seconds to builds oil pressure.
