Batteries for new Northern Lite camper

Hi, My 2008 NL 10-2 CD SE came with two 24's. They were good for a couple of nights boondocking until we started using 2 cpap's. But, they are really difficult to service with the tight fit and without the sliding trays that some campers have. I tried a profill system but one of the plastic nipples broke and flooded a battery compartment with acid. After I added 200 watts of solar, I decided that I had enough of battery problems so I pulled the trigger on 2 Lifeline 6 volt AGM's. They are maintenance free and I was able to set them on their ends for a good fit and easy hookup. Expensive, but money well spent in my opinion. Now we can run our CPAP's and watch a movie 3 nights in a row without hookups, even longer if we're driving everyday. By the way Trojan 105's are too tall to fit, I looked into that pretty thoroughly. Maybe your dealer will credit you for the 24's if you want to go with something else. Good luck and I hope this helps. -Mark.
