Battery charging in Cargo trailer

I camp out of a small cargo trailer. Currently have it set up on solar with 2 6 volt batteries. Long story short I am looking for someone with experience charging batteries off tow vehicle that is not set up with tow package. I have no inverter in trailer, this is not an rv. It would need to go from tow vehicle battery ? to trailer battery? Needs to be fused? Need some kind of charge controller so batteries do not overcharge? Thanks in advance for help.

    What is your tow vehicle?
    Typically without a factory setup the easiest way is to go buy a battery isolator and run a dedicated line from the isolator to the 7 pin plug at the back of your tow vehicle. Then run a wire from the trailers plug pin to the battery plus. Correct pin outs can be found all over the the internet. Just search for Baegman wire schematic.

    It would be an odd tow vehicle that doesn't have a trailer connector. You may need to get the socket added but U-trailers will be happy to do it for you. Or buy a kit and do it yourself.
