I am not yet a J-30 owner but hope to be soon. I am wondering if anyone has experience in mounting a pair of Group 31 (13"x7"x10") batteries in place of the standard group 24s (11"x7"x10")? I know the compartment in the port quarter berth has a molded fiberglass tray sized for the 24s, but how hard would that be to modify to accommodate a couple more inches. Anyone done this? Any other suggestions to increase the total Amp hours of the battery bank?
