How much battery charging from alternator?
Having spent a few years here I often read about the concept that while a typical trailer wiring connection from the vehicle to the camper will supply 12V, it is of low amperage and as such the camper...

OP revisit.
So I have backed off from regularly visiting that RV Solar forum because I really can't believe the advice I read on it based on my own experience and what I've learned on these forums. The latest eye roll was a recommendation of 500 watts of solar for someone's 2x6V GC batteries and a follow up post of needing more like 900 watts due to the poster's latitude in NY.
But one topic that I contributed to but am now uncertain of is the battery power supply for trailer brakes when break away is engaged. I said the camper battery supplies this power and is one of the reasons that a battery is required in an RV trailer. A response was that trailer brake system needs to be completely isolated from rest of camper system. I know that the wiring for the braking system is not part of the RV power distribution panel but it does use the same battery, right? There isn't another small battery for this purpose hidden away somewhere? I know that cargo trailers need a small battery for this purpose, but I've been under the impression that in a camper it just uses the main 12V camper battery.
