I recently purchased a 2007 Northwood Nash 22H and I need to replace the current single group 24 12v battery. After measuring my existing battery tray, I've determined that I cannot fit a pair of T-105 6v batteries due to the height. After much research I believe I've settled for a pair of Trojan SCS150 12v batteries. However, according to the specs on the Trojan website, this particular battery is 11.3" long. I cannot seem to find a compatible group 24 battery box that will accommodate this length. I cannot fit a group 27/31 battery box in this location either. For those of you that have, or have had, a Trojan SCS150, what do you use for a battery box?
