With the two T105's you have 115 AH usable at 50%. I had 4 t105's in the previous MH and they served me well. But now I have moved to a Class C with only two batteries and am running two 12 volt deep cycle and they are doing well also. If I replace as these are well used but still doing good I will go to the Interstate 160 AH 12 volts which will be 320 AH so at 50% I have 160 AH. Now with all that said with the two battery system balanced to the usage in the smaller MH this should be as good or better that the larger MH with the 4 T105's.
We dry camp a week to 10 days then to a hookup for a week then back to dry camping and the Gen time for the two verses the four is comparable.
