Floridian, If that preheat is a momentary "on" toggle it may be hooked up to an ether solenoid in the engine room. My '78 had one. There was a bracket that held a standard size can of ether that was plumbed to the air intake tract. It leaked ether so I never used it. If you are near 30 degrees a good shot of ether into the intake while cranking will probably start it. It would be good to have shore power or have the genny already running so you can merge the batts to help spin the starter motor.
My '93 has a receptacle on the bulkhead like Tf is describing. Mine seems to be dead but I never run in freezing weather so I havent checked it out. I didnt think about there being a switch for it.
Some old bus-nuts friends used to line a flat pan with charcoal briquets. After letting them burn until they turned white and smoldered they would slide it under the engine to warm the oil. I am not recommending this and If I tried that I would burn it to the ground although I never heard of anyone having that happen.
