Sounds like you found a great rig!
Another thought on your A/C - When we purchased our TC used about 12 years ago, we had a dealer install an A/C unit before we ever used the TC.It was and still is our first TC. Now we realize that we do almost all our camping in the PNW so I think for us the A/C was a mistake. I can only think of 2 times in 12 years that we have actually used the A/C, and we really could have done without it those time. The extra height is a real hassle for us storing. I would have had a lot more options without that extra height.
Just a thought before you "cut the hole". I do get the attraction, and if I were expecting to do a lot of camping in the south west I would have a different opinion. I guess the point is, and just a suggestion, to think about where you plan to use your camper before you cut the hole in your roof.
