Direct Charge Circuit
I would like to run a direct line from my truck alternator to the house batteries in my fifth wheel trailer. Has anyone done this project that could offer some suggestions on how to and what materials...

Just as a reference point:
Our motorhome came with 6 gauge cabling built-in between it's Ford alternator and the two coach batteries. Of course, the engine battery is also connected to the alternator - so we have three 12V batteries all in parallel with each other getting charged by the Ford 130 amp alternator when going down the road.
I have a coach battery digital ammeter mounted right on the dash and I've seen the alternator dump up to 50 amps through the 6 gauge cabling into the coach batteries when the coach batteries were discharged but with the engine battery fully charged. Of course our 6 gauge cabling is probably only 6-8 feet long going from the alternator to the coach batteries.
