We have the fwd battery boxes in our 78 Ambassador, and the Group 31's won't fit in those compartments...
I'm in the Battery biz, and the 13 inch length (vs the 12 in of the Gr-27's) is just to long...the trays inside the box fit the Gr-27's just perfectly...
BTW: most good, flooded cell deep cycle, G-27's are rated at about 105 Amp Hr, while the deep cycle G-31's can be rated up to 140 Amp Hrs...
The group 29 is also a 13 inch long battery, usually rated less than the G-31 sizes...
I wanted more total Amp Hrs, so I mounted a third group 27 battery in a box on the tongue, behind the propane tanks...I used the same size battery as my other two, so when they are all hooked in 'parallel', the cell sizes will be the same for equal charging/discharging...
