Battery Upgrade
First let me set the stage. We boondock 1-2 weeks a year. The rest of the time the trailer is plugged into shore power either in storage or at campground with hookups. We have one house GP27 wet ce...

I am looking for guidance on AGM batteries (6V or 12V) and brand. I have learned the Trojans are the best but are they needed for my situation (1-2 wks a year)? I suspect upgrades to the charger will be in order so would like opinions on that. I believe Progressive Dynamics is the preferred brand. I also believe the 14.8 is recommended for AGMs. Is the 6AWG sufficient for a 45A upgrade?
You've learned Trojans are "the best" eh? :R We too only dry camp infrequently and for my use a G31 Deka AGM serves my purposes fine. At times when I might want to power my 1000 watt PSW inverter I merely load support it with my truck and it works just fine for running our toaster & coffee maker, avoiding the need for a second battery I'd otherwise have no need for. East Penn is very specific about requiring temperature compensated charging but nominally their Deka brand AGMs want to see a 14.4 volt bulk charge voltage, no higher. You could replace your converter but I chose to simply turn my WFCO off and instead use a stand alone charger capable of the required 14.4 volt bulk charge voltage and located it next to the battery so voltage drop due to cable gauge is a non-issue.
