HAB floor thickness?

[headlight]

Does anybody have a rough idea of how thick the floor is on my Swift Suntor ?
I'm getting ready to put a hole through the floor to run cables to a second leisure battery and would like to make sure I have hole cutters and a fitting that will cope with the thickness.

I would suggest that it's no more than 3/4".
but I'd just drill a hole small enough to take the cable and seal with silicone.

Normally a foam sandwich so around 28-30mm. Drill a pilot hole and use the cutter from both sides.

Our Elddis floor is 40mm thick, but as two says, just drill a hole the size of the cables and silicone, that's what I have done.

Have a look at the cut out breather in the gas locker, you should be able to see the depth there.
