Gday

im about to take ownership of my new camper and just want to know if im on the right track.

in my patrol i have the normal everyday dual battery system. Now i have heard of some people running the power to a plug at the back of there car from the aux battery and plugging straight into the camper to charge the camper batteries whilst in motion.

my question is due to voltage drops etc would it not be better to do as said above but run a dc-dc charger in the tool box of the camper to boost the charge given???

any help greatful cheers
