IMHO, you have to be a complete moron to get to the point where your battery case is cracked and the acid leaks out. Repeated neglect over a long period of time is the only way a battery will leak its acid.One purpose of the battery box is to contain leakage so that it doesn't spill out and damage the surrounding material.
If you are using any common sense - taking the battery out when the camper is stored or even doing minimal maintenance to it - you do not have to worry about acid leakage. If you haven't used your camper for a half dozen years and you have left the battery in the box, then you probably deserve the damage that results from a leaking battery.
In order for a battery case to leak, first you literally have to have a completely dead battery that is WAAAAYYYY beyond it's usefulness and old. Second, you have to repeatedly go through a dozen or so freeze thaw cycles to get the case to expand and contract so that the case is compromised by fatigue and cracks.
Depending on your climate, this could take years if not a decade to get the battery case to crack. Here in Minnesota, it would be a shorter time, in the southern States, much longer.
In short, drill your drainage holes in the battery box and don't worry about battery acid leaking. For you morons with leaking batteries - please make sure you take the battery out of the box before you drill your drainage holes and make sure you use protective clothing and eyewear.
