7 pin to 12 pin and Solar charge

[Moxley23]

I've got a 7 pin, but Expanda with 150L fridge and battery comes with 12 pin plug. I want to be able to charge battery down the track with portable solar panels. Should I get Jayco to change the 12 pin to a 7 pin and keep the battery wires separate with an Anderson plug and then install an Anderson plug on my car, or should I change my car over to a 12 pin and then cut into the battery wires on drawbar and put an Anderson plug connection in so that I can discontect and charge from portable solar panels that way?

Me personnally, I've gone with a 7 pin large round plug because I find they give a better more reliable contact and an Anderson Plug for the 12V from the car. I went this way so that I could run 6B&S cable through the car. This way I reduced the voltage drop when drawing high currents for charging and running a 3-way fridge and the 12 pin trailer plug can't accomodate the really large cable sizes. When I disconnect from the car I can add an addition battery to the trailer by connecting to the Anderson plug or attach solay panels for charging.

I'm with gwadir. I have 7 pin on car and van with heavy duty wire through the car. As a side note, do you have a heavy duty 12volt pump also? You can mod that to an Anderson plug and run from the back of you car also if you have the Anderson plug setup. so convenient.

That's sold me. I have a compressor. So adding an Anderson plug with heavy duty cable to the car will allow me to plug in other accessories so much easier. Brilliant. If I kept the 12 Pin and put two andersoner plugs between battery wires on Van side of 12 pin plug I wouldn't have had that ability.

Thanks.
