I would look at the owner's manual for the chasis to see what Ford or whoever recommends. Then I would cross reference that number to th Diehard brand.

As far as the coach batteris are concerned, I have seen a lot of discussion about series 6V and parallel 12V. Since I do not boondock, and the Sun Voyager spends most of its time hooked up to the converter, I opted for the 12V. I was able to crawl under the RV to see the numbers for the coach batteries. My batteris are located under the "hood" forward of the engine.

I replaced all three batteries with batteries from Auto Zone. They should check around and see if there are batteries less expensive that what they sell. Then, they will match prices.

I marked all the leads before disconnecting the old batteris, and I changed all three batteries in about 45 minutes.
