I can't find a clear answer, but I believe that you are correct in that the 12+ is always hot meaning you could definitely kill your starting battery.
I guess you could install an isolator after that plug to keep you starter battery from draining.

I think with deep cycle batteries you want to charge them slowly, in which case there wouldn't be any reason to upgrade the wiring. Maybe just add a relay so that the 12+ on the 7 pin only has power when the ignition is on. (Can you do that with wires that connect two batteries?)
Not necessarily true you're not starting a motor or running a large electric motor like on a winch you're just charging a battery. So the smaller wire will do the job in fact maybe better then a larger one because it will charge slower instead of a hot charge. I would have to measure it but it a deep charge is considered 2amps or a trickle charge if you will but I'm guessing maybe get more amps out of it then that. Just some food for thought. Oh I can't measure the amps for you guys a blew the amp fuse in my meter and don't have any spares left.
