My name is ***** ***** I will assist you with your question today. I'm an independent contractor and I don't get paid until a rating has been made. No rate, site gets it all. We can go back and forth as needed to help resolve the issue you are having. Follow ups are free after ratings, so rate in confidence! Will the battery just be used for powering items in the camper or will it be used for other purposes, like starting a generator? I ask because there are two ways to connect the battery. CLICK HERE for the typical way the older Fords connected the batteries. CLICK HERE for the other way. On the second picture, that is how the newer F250s connect it. On the 197's models, they were more of the first pic where the cables went right to the starter. Now if you are just needing it to have extra power (longer use) to power up some lights for the camper or a trailer and still have some start available, use the second pic. It will use up one battery at a time. You then will want a power switch installed like a cutoff switch so when the batteries drop below 10 volts, the switch engages and cuts the power to the camper so you still have battery life left to start the vehicle. There is also a way to cheat this which is what I do when I go tent camping now. Get a battery charger with a invertoer that you can clamp to the battery. Hook the battery charger up to the invertor and connect it under the hood. Then you will have a constant battery charge going while using the battery to power what you need. It is a old outdoorsman trick that will make sure you always have a full battery and still power your camper all night long without the use of a generator. In case that is what you are tying to do.__________________________________________________________________________________________________________________________You want a 5 star service and I want to provide a 5 star service.
