If using the stock 6 or 7 pin connector 24 hours of towing might work.
The charging wire needs to be beefed up considerably. Even better is to add a 2nd external diode to the oem alternator.
While I agree that almost ALL OEM vehicle charging ckts need to have a larger dia wire I would think that your extra diode comment as generic and non specific as it is would help since any diode will have some voltage drop so the full alternator voltage will suffer when any diodes are in the charging ckt. This is why some of these battery isolators that use two diodes and generally a poor idea and result more often than not in poor battery charging.
