Battery mounting advice needed

[Kosmic5]

I am a new owner of a 2970RL and want to transfer my two 100ah AGM batteries from my old camper. The batteries are about 1 year old and lithium isn’t an option right now.
It doesn’t look like I will be able to get both batteries between the angle in the frame. Does anyone have advice on installing them above the frame? I don’t want to do anything that could mess up the new steel tubes.

Do you have room to rotate them 90 degrees? If so get some angle iron and make a new battery tray on top of the original one.

I had roughly the same issue when I installed 2 6v. I just filled in the space between the angle beams with some plastic (Trex-like) decking to make a level platform. Plastic to avoid moisture/future rot issues. Bought a couple pieces of the decking at the local big box, in their "damaged" area for much cheaper. Screws from the battery boxes into the decking. Straps around everything as belt and suspenders. 5 yrs, and 15,000 miles later, still looks like the day I did it.

I had some angle iron and a welder, so I fab'd a tray wide enough for two G29 12V battery cases that sits on top of the frame tubes. When I switched to two 6V batteries they fit between the frame rails.
