The 6-way trailer plug is near useless to charge a camper battery. The wires running to the plug and socket are far too small. Ridiculously so with regards to charging. The wiring is merely adequate to -maintain- a fully charged battery full.
Hundreds maybe thousands of campers are forced to upgrade to a genuine charger socket and plug. A second socket and plug devoted to battery charging only.
Six gauge wire is about the size of a fat pen. You need to use circuit breakers at each battery to protect this wire. I use small heater hose sliced lengthwise to use as a sleeve over top section of wire that passes under the truck. Stay away from exhaust components.
Have a trusted BODY SHOP make the hole (2 wires fit into one plug and socket hole using twin contacts).
Then you run a pigtail PLUG that will reach the socket mounted in the pickup bed fenderwell. The pigtail positive runs to a sixty amp breaker you purchase and install yourself.
You do -not- have to run a ground cable the full distance.
You DO have to make a ground cable six gauge, that connects between the engine block and chassis frame. On the same piece of steel (no riveted joints in between!) connect another 6 gauge ground and that will run to the new socket mounted in the pickup bed.
Then you will be happy. I'll bet the supposed battery feed line is 12 not ten gauge. A sad joke.
Keep us posted about the 1314. Sure Power went to hell when Cooper Industries bought out Sure Power from the Scheidler family. Ralph Scheidler's people made good products. Cooper of course wants to milk the cow. Bet there are weekly meetings now to discuss buying from the latest cheapest electronic parts sources in China.
If you insist on sticking with the original 6-way connector and socket you are going to regret it.
