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...

Those trailer owners that think a full charged chassis battery won't let other paralleled batteries charge, are invited to look at my MH w/ an ammeter shunted right at the alternator. Yeah, that's what I have, and you'll see I constantly get a 60 amp charge to 50% discharged house batts, w/ a full charged chassis battery.
Easy. Measure the voltage at the alternator. Then measure at the 50% low GC2 batteries. Post the measurements.
Then trace along the path to find the voltage drop. Improve those areas until the amps start moving. You should aim for 0.2 to 0.4 voltage drop max between the alternator and house battery. The lower the voltage drop the better.
