campadk andasherkobin,
Great report! Last year, I was offered the original prototype of the 75th that David Winnick built. It is the only '06 75th Anniv. model. I really lusted for that, but just couldn't swing it at the time

.
Anyway, you can get much better charging from a better converter with 3 stage charging like a WFCO or the NEW Parallax ParaMode 4400........OR you can hook up a small 3-stage electronic battery charger (about $50) directly to your batteries and bypass the converter entirely (this will need a battery disconnect on the neg. side of the battery cable to isolate them, or use your battery disconnect switch in the trailer).
You can also change out your batteries to AGMs and get a lot more useable amperage from them. I put a WFCO converter in my 19CCD and 2 6volt GPL-4C AGM golf cart batteries in it and I have lots of juice. One of the advantages of ANY AGM battery is the much quicker re-charge times due to the lower internal resistance of the battery.
Another option might be to use LED lighting in the trailer. There are several threads on this, and I have found a light that is a DIRECT REPLACEMENT for the halogen lights that are in the Bambis.
Just a couple of suggestions to keep you running in the boonies.
