A/C flow close to water heater isn't an issue in my rig. Maybe in some rigs it is. In my trailer this heater is far away in a storage nook, a limited air exchange with the room air.
Slots on battery box are needed for fumes venting rather than for heat exchange. You can't do much for battery cooling if it's outside, but you can (and should) use on-battery temp sensor when charging.
I think fiberglass insulation in RV walls are same 1.25" or 1.5" as styrofoam. Same R6 or R7 value. It's the missed spots (and framing if metal) that are a problem. Cold spot around my furnace was huge - all the outside furnace panel. I installed propane heater inside, removed the furnace completely, and put insulation in the wall there.
