We tow a 4WD FEH four down which had the same basic components as the FFH thru 2012. We do follow the instructions for leaving the key in ACC position and use a charge line from the RV..
Yes, you bring up a good point here - With Ford's hybrids, a charge line from the MH is almost a requirement.
With ours I confirmed with an ammeter that there is a constant drain on the battery of around 3 amps when you leave key in ACC position. Even more if you have a supplemental braking system pushing on the brake pedal, as Ford's electric powered brake assist stays on all the time when towing.
With these hybrids, in most cases you're going to have to run a charge line, or will deal with a lot of dead batteries and jump starts. Very, very easy and simple to do, though, and eliminates worries completely of running down the toad battery.
