I'm failing to see a purpose:
- If you are towing, you need a battery if for no other reason than the emergency brakes if the trailer becomes separated.
- If you are stationary, the battery lasts pretty much forever because it's never run down.
By the time you update all the 12v devices, you are likely looking in the thousands of dollars to pay someone (cheaper obviously DIY but still far from free). All to save replacing a $50 battery every 5-10yrs.
