Thanks Brandy. Yeah, Hubby says cutting into it shouldn't be to tough but before I let him head out with saw in hand, I thought I'd ask the experts. A lot of the egg owners here are very handy!
I think the hole we need for frig vent will be about 8" x 14", so do we have to be concerned with the structural integrity? Are there other parts we'll need like ducting to vent or is just giving the frig ventilation good enough. I've looked at our Pop up and don't see anything special added inside, but that's a whole different breed. Maybe others with a frig already installed in their eggs could post photos for comparison.
As far as our Pacer goes, the frig is set under the kitchen counter, similar to most scamps, etc.
