battery location inside August 14, 2009, 02:30:32 pm Yahoo Message Number: 104827We removed the furnace and put 12 volt deep cycle batteries from Costco in that compartment. It will hold 3 but we put two. The vents from the furnace will vent the batteries. So far that has been a good solution. We left the isle wall open and wedged a 600 watt inverter against the fresh water tank. Here is a picture of the compartment where we removed the furnace for the batteries: http://www.flickr.com/photos/safoocat/2932629262/in/set-72157607826626518/ The vents can be seen in the back. Here are pictures with the batteries installed: http://www.flickr.com/photos/safoocat/3031359806/ http://www.flickr.com/photos/safoocat/3029029068/If anyone wants the furnace they can have it. It worked fine when we took it out last year and it's been stored inside since then, free to a good home. best, Michelle Ress++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Additional batteries would likely have to be inside somewhere, which means all four would have to be replaced with AGMs. (wet cells need to vented to the outside) I have not wanted to step up to that bar yet The only thing I have done was to replace the HPV-22 with an HPV-22B (direct swap). So I could turn the dumb thing off with a switch. (I'll never understand LD for not offering the B model)-Dave '06 MB, Indianapolis
