I have a Jeep Cherokee that when tent camping I pull a small off road trailer.
The trailer has on board water, dual batteries,inverter and charges from solar and shore power.
I want to also charge the batteries from my Jeep while towing. I have setup an isolator and want to fuse at both sides of isolator near battery.
My question is if I use a 30 or even 50 amp fuse is that enough? I know the trailer will not draw a lot of current just charging. BUT asking electrical question: The Jeep side I will hook to battery and fuse before the isolator. On startup and say I have to use my winch there will be a lot higher current draw... does it effect that fuse on the charging side... would it blow every time or does the fuse only see current draw from the trailer.
I know I can unplug trailer if needed to winch but don't want to at each startup.
What am I missing or am I overthinking it?
