Ok so the trailer wiring with batteries, 12v and converter is all good to go. The way you describe the breaker box and your image is the same as what I have drawn up. I may have explained it wrong and my diagram of the box may have been messy with wires crossing over, but it is wired the same way you mentioned. So I should be good on that as well. As per the trailer diagram, I was looking into battery monitors this morning. It would be good to know battery charge level. How would I wire one of those in? This is the one I was looking at. www.flickr.com/photos/53634851@N03/46795849444/in/album-72157682956476004Looking like brass sampler goes in between the negative cable and ground in J-Box. Then a 12+ wire from the battery goes to the brass sampler too. Finally, a group of smaller wires go to the monitor. I will have 2 battery ground wires, A negative to trailer frame and a negative to J-Box. Does it matter to the monitor that I have 2 ground wires? Can I put the brass sampler in between the battery negative and the J-box? Thanks.

For some reason, the image link is coming up my electrical box display...
I'm thinking follow the instructions for the battery monitor. Not sure about the brass sampler, as I've not bothered with a monitor. .

Sorry, here is the link for the monitor. AiLi Voltmeter Ammeter Voltage Current Meter Voltmeter Ammeter 100V 350A Caravan RV Motorhome 999 AH a.co/d/gn2oF5uHow do you keep track of your battery charge with no monitor?

A simple multimeter will keep track of the battery charge. There are several types, the cheapest being Harbor Freight's, about $7. Less than 30 seconds to do the test.
Keep in mind we are working on vintage trailers here. They had far fewer electrical demands and much simpler systems than more modern trailers. Most small trailers did not have converters prior to the 1970s. You can add as much as you'd like. I like to keep mine simple yet ready to boondock. Canned ham trailer manufacturers used many ingenious ideas to keep things working off grid.

I am trying to make everything in it be set up for off grid camping. For this reason most of everything I’ll be using is for 12v accessory and propane heat/hot water/stove top. I almost opted out of the breaker box but figured I’d add one since I’m doing everything new and thanks to you all here, I’ve started running wires. Well figuring out what wires belong to the lights at least. I pulled this nest of wires out of the trailer today. It’s hard to imagine that all this was used to lights(which run off 2 wires with wire taps), water pump, heater and taillights. The wires must’ve been doing something else, but I don’t see what they could do. i.imgur.com/Sjv7lKc.jpgi.imgur.com/HIGKqWZ.jpgHere’s some photos of the converter. 1 110v cord, 1 red wire going to the back of the trailer, I didn’t follow it enough to see where it went and 2 wires going to the nest near the power block…. i.imgur.com/b5oDiMa.jpgi.imgur.com/ZC1dcgA.jpg
