But you are only down 30% so the charge will slow as you get above 80%. RJ is talking initial amps when the battery is way low. And if I know RJ he says 50% but they are probably even a little more discharged.
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?

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.

Has anyone done this project that could offer some suggestions on how to and what materials used? Any help will be appreciated.

I'd like to make a request to have a separate TCU sticky thread on upgraded charging systems. I've posted about my system in my camper mod page, and there are a couple of other threads floating around about doing the same thing. This topic comes up often enough that it seem like a good idea to have a tread with one stop info on people's various systems.
I'll start with a repost of my setup, and I invite those in the 6 gauge, 4 gauge or 2 gauge club to join in.
I listed a few choice threads that were pertinent at the time I was doing my upgrade project research.
Links are halfway down the page and as the post goes on, there are references to other threads as th...
Here are a couple links to other threads that have been of great help doing this project.
Matthew_B, Alternator Charge Cable Installation to TC.
BC Sierra, Alternator Charge Cable Installation to TC.
JoeChiOhki, Power Converter Thread.
Battery Discussion Thread
Battery Warmer Thread by Sleepy
My earlier discussion thread.
My original post relating to installing large 4 gauge wire.
This is the first thread with a report on charge cable performance.
