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.

Rich can you describe how you achieved this rate of charging? I only see 5-6 amps of charge from a 180 amp alternator and 2 6 v batteries at 50% SOC.

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.

My MH is winterized now and 1200 mis away. But if I remember correctly after a week of dry camping my chassis batteries were depleted about 30% and the 2 6v house batteries were 50%. Voltage at house batteries were 14.1 v and house were at 13.7 or 13.8 v. On a 5 hr drive home at 60 mph I was reading about 5.5 amps going into the house batteries. Would a voltage drop of .3 v cause this?
