Relocating battery
I am looking to upgrade my battery to two golf cart's. However, I can't handle the additional tongue weight, so I was considering relocating the batteries to either under my rear bunks or on the floor...

I'm probably one of a handful of guys that have done this, relocating LA batteries inside an RV. It's usually more than the average RV owner wants or needs to do. I did it for weight considerations.
I built my own box but most guys would find it easier to buy an off-the-shelf dual battery box and install a vent. The vents to and from the box do not have to be that large. The amount of hydrogen gas displaced during charging is not a large amount. Yes, it's a good idea to have a lower mounted fresh air supply hole in the battery enclosure to provide gas flow to the outside. Hydrogen is much lighter than atmospheric air. If you're concerned about hydrogen flow back out of the air inlet (really shouldn't be a concern), install a flap on the inside of the battery box or put a small fan onto the air inlet.
