Looking for input/feedback on where a battery bank and inverter would fit on a 2001 410 Sundancer. Im considering a 4x6v golf cart battery bank (wet cells) and a Magnum inverter. I removed the molded cubby hole right next to the captains chair and there is a fair amount of space between the inside liner and the top deck. I think enough room to get the 4x6v golf cart batteries in there. I ordered a battery box off Amazon to see what will fit. The Next question is ventilation. The area in question has several large holes leading up into the arch and down into the engine bilge. How much ventilation is required? The final question I have to answer is where to place the inverter. They do not recommend placing it in same location as batteries due to gas produced. Any body install an additional battery bank on a 400/410? If so, where? Or, did you beef up the house bank and call it good? Pictures would be awsome.
