I cut a big hole!!! IN MY CAMPER ROOF

I haven't touched it. Wasn't that long ago it was snowy, cold, rainy, barely up above freezing to maybe 40. Funny I was just thinking of getting it uncovered RIGHT AFTER I get the camper done. I want to get this DONE or at least useable and watertight

That rear vent should work GREAT. It is going to take up the entire vertical area of the rear area, and ?? 2/3 or so horizontally. The camper side windows both slide open / screened so there should be lots of ventilation.

The top, I found, when drilling it, is actually "double walled." the drill goes through and bangs against the other side, I used 1 1/2 " screws so it is quite thick. This should help maintain some insulation in what little cold use it for.
