Default 95 BMC battery fitment question

So I have discovered while reading that the new batteries that came in my bus need to be changed out. Sounds like the compartment is not properly vented for the wet cell batteries that are installed. I’m not to upset since they are not deep cycle units and don’t seem to have much capacity at all. I’m thinking that I can just squeeze in 6 golf cart agm batteries on the bottom shelf. Can anyone confirm that for sure?

With our current configuration , only 4 batteries will fit in ours . Haven't really measured to see if i could change things around to fit more. I can fit taller batteries out of a forklift or floor scrubber.

We are running regular 6 volt golf cart batteries.

I believe those are too tall for us. I'm thinking we only have 14 inches of room for height.
But that is close to what i plan on putting in a few years from now.

My 1997 seems to different from most as I have two group 31s for engine start batteries and three 4D AGM deep cycles for the house batteries.

On the top shelf are the group 31s and one 4D.
The bottom shelf has the other two 4Ds.

Most BMCs I have seen were set up with 4-5 group 31s. Two non-maintenance start batteries and the rest were deep cycles for the house.

I have 6- 6 volts, Trojan T-105 size, 4 on the bottom and 2 on top next to the engine start battery’s. The wiring is 3 sets of 2, each having the same length short jumper and same length home runs back to the combiner post ensuring all charge and discharge at the same rate. This set up has worked great for 13 years. I got 10 years out of the first set of t-105s, I never let them get below 12.2 volts

I think to use L16 I would need to lay them in on their side and I could fit 4 side by side. Would 4 L16 be better than 6 gc2 format? Less connections I guess.

Looks like 4 is l16 would be about 780mah while 6 us agm2000 would be 630mah. About 1800 for the agm2000 while the l16 would be about 2040. Ouch! That’s from online. Shipping would have to be killler. I’m going to check around locally to see what I can find.
