When towing for an extended period of time, start the vehicle as often as possible and allow it to run for five minutes to prevent battery drain.
Well that depends on a lot of variables. I tow an 07 Malibu, lights are hooked up through a diode block. Pull the fuse the owners manual says to, actually I installed a switch, and there is no battery drain. Well no more than if it were sitting in the driveway so there is no need to start it. If you have a brake system that runs off the toad battery that can drain the battery but you should hookup a charge line from the MH in that case.
BTW: 5 minutes of run time will do little to nothing in the way of charging the battery.
For those vehicles that require starting and running the engine after a couple of hours or so is not to charge the battery (altho that helps).....I think it is more to lubricate the transmission.
