The 6V batteries would not fit without this modification for our 25FB. We could not have done it on our own but if you are handy, it probably would not be too difficult.
Thanks Sporks, I was referring to you. I was about to pull the trigger on 2 Lifeline group 27's 100AH which would fit sideways according to Lew to avoid modifying the box, but after more consideration, decided that I will go with the 6V Lifelines as well. Hard not to when you can get 220AH for about the same price as I am sure everyone who has done the upgrade also concluded. I have the factory solar which I will keep for now to keep them charged up and I have the new Champion dual fuel 3100 inverter/generator to run the A/C or charge batteries as needed. I may get a portable solar panel so I can park in the shade and still charge batteries in the future and get a new converter....Oh it adds up quick! Thanks for all your help, this forum has been a wealth knowledge! Special shout out to Lew for all his help as well!
