I have a little Bantam T3-C trailer I restored that I pull behind my FJ60:
I want to add a battery setup to it that I can use to power things while I am at camp. I don't really know much about how that's done. Here is what I want to be able to do:
1. When towing the trailer, I want the batteries charged by the tow vehicle using the 12V hot lead in my 7-way connector.
2. When at camp I want to be able to charge batteries using a solar panel when A/C power is not available while at the same time using them
3. When at camp I want to be able to charge batteries using A/C power when available while at the same time using them
4. When the trailer is sitting not used at home, I want to be able to plug in the batteries to A/C power to trickle charge and maintain the batteries
5. When at camp I want to be able to use the batteries to run either A/C devices or DC devices as use demands without having to switch between A/C and DC
6. When at camp have USB ports available for electronics
7. Would like a meter of some sort to tell me when the battery charge level and current load, etc.
I am not really sure how to achieve this without cobbling together a bunch of devices. The way this could be done I think is by using a combination of an inverter charger with USB ports, a Solar charge controller, maybe a trickle charger for use when sitting at home, and a tow vehicle battery charger like this:
I am not sure how all these would work together. Can I just add the output (charging side) side of each of these devices to a battery and have each one charge the battery depending on which one is being used? Or do I need some sort of voltage sensing switch to prevent the charging voltage of one device to impact the others while they are all connected to the same battery, or does it not matter. Is there an all in one device that can do this sort of thing or am I stuck building a custom charging setup to do what I want to do. The trailer is quite small as you can see so not a lot of space for this stuff. I would like to put it all under the trailer somehow in a weather proof box. Thanks in advance for any ideas on how I can achieve this.

Towed Battery Charger Plus for flat towing
RVi Towed Battery Charger Plus, charge line replacement for flat towing a vehicle. Great peace of mind for the towed battery while towing a car behind a motorhome. Often used with RVibrake. TBC+
