Thank you everyone for your responses!
I'm thinking Gumb is right, wait until it arrives to make the final cuts. I'm tiling the top so that's the safest way to go. As 12x7 suggests I will certainly post pictures when it arrives.
Spook and macca, we ordered it from a local ACE Hardware for $1,199.00 with a 2-3 week delivery. I'm very eager to see how well the air hinge works.
Thanks 12x7 I will reach out to them for some assistance. I sure wish the new models were in the stores. This would make things much easier. More to come!
I'm guessing since you bought it from Ace Hardware you live in the US?
