I have an old Mopar/Chrysler auxillary hot water heater with heat & defrost ducts I was going to put in my '73 Land Rover, but never did. I don't know if it's 6 or 12 volt as a piece of the insulation on the wire is cracked & I don't want to test it. The fan does turn freely by hand though. This would be a perfect heater for your F series.

$40 plus shipping.

It looks to be a pickup heater from the 40s. I'm guessing 6v, but it's easy enough to convert. It's not "self contained" though. It needs water from the engine.

It would be worth more if you knew what it originally came out of. Some poor mopar soul has been looking for that POS for a year.

You know after I put self contained I thought someone might pick up on that, I corrected, thanks. I know it's def worth more than $40 to a Mopar fan, I'll try & post on a Mopar site.
