But it’s a waste of at least 40Ah of usable capacity that could be put to good use and at the same time be a considerable cost saving.
Note, if you did have one of my isolators, you would not only have that extra 40Ah available, but you would need a much shorter drive time to replace used battery capacity as compared most likely extend the operating lifespan of your cranking battery.
Next, if you have a lithium in your tow vehicle and lithiums in your camper trailer, you are going to need two separate DC/DC devices. Thats a huge setup cost.
You would be far better off leaving the tow vehicle setup as is and just concentrate on your camper battery setup.
