Battery Charging on Truck Camper

Put a solar panel on the TC roof & your batteries will be charged on the road, at your camp spot AND when it’s parked at home…. My batteries are fully charged EVERY day by sunlight…….

Old camper with a mfg specific or obsolete plug, cut the sucker off and install a matching 7 pin. Then everything is the same, no mix n match/adapters or old plugs. Easy to wire the 12V + pin for charging.
Or do the same but also install a dedicated charging circuit with or without a DC DC charger depending on how serious you are about charging off the truck.
Good luck!

Consider solar for primary recharging. No need to be driving.

Thanks all! Now I know how to start.

You get something like this: https://www.adventurerv.net/lance-6wire-plug-truck-side-p-1484.html?osCsid=07n2jvaf0hp8hrbejila92vep7 and then put a 7pin adapter on the end to plug into your existing 7pin plug, then your 6pin plug goes into the other end.

Can you purchase? Probably not. Most likely the camper is wired in a non-standard way compared to a trailer.

That was what happened with my Palomino. It has a standard 7-pin plug in the front, but it's wired different from a trailer.

You'll need to figure out which pin does what, and if there is a 12V pin. Draw a picture of the connector on a piece of paper with plenty of room around it to make notes. With a battery in the camper, use a piece of wire to briefly jump any two pins together. Just a quick tap. If you get a spark, you found 12V and ground. To figure out which one, switch to a different pin on one end of the jumper. If nothing happens, you now know which of the first two pins are 12V and ground. If a light comes on, again, you know which is which. Take notes. Now start poking between the 12V and the other pins on the connector and see which lights come on as you do that. Take notes.

Now you can get a 7-pin, a 6-pin and enough cable to reach, and make up your own custom connector.

In your case it will be easy to know which end plugs into the truck and which plugs into the camper. In my case I put it in backwards once and nothing worked right. I had to raise the camper back up to get at the plug in my bed to swap ends on the cord. Then I wrapped tape on the truck end. T is for tape, and for truck.

For better results, invest in a dc to DC charger.
