I want input.....I want to put a battery on my popup camper and set up a charging point
in the back of the XK. This would allow me to plug the trailer into the XK and charge the
battery if I am not close to electricity.

The camper has an inverter now. I am going to add 2 batteries to it so I am looking for a
way to charge it.

I was just reading Adondo's reply on the Roof Rack lights so I hoped he or someone will
have input for a plug.
