So it turns out that to install a
battery in my new-to-us
Casita, I'll have to install and vent a
battery box. This means I need to drill a vent hole in the outside of the trailer and a drain hole through the floor.
I'm nervous! My plan is to simply get a 3" (or whatever size matches the vent) paddle bit and drill through the wall after blading out the wall-carpet. Will it be as simple as this? I've never drilled through
fiberglass so I'm not sure what to expect.
Also, how far away is daylight when drilling down through the floor? The
casita has a
fiberglass frame underneath, too, and I assume a wooden subfloor above that, and then the carpet. Does that sound about right?
