Glad you're trying it first..
As near as I can tell most of those penetrations go through the aluminum frame around the door. Id be surprised if the Carbon had a substantially different door than other setups. I *think* I've seen Carbons optioned with the ramp patio, but I believe my dealer told me that it wasn't available and wanted to sell a Fuzion.

Shows a carbon with the ramp patio. Door doesn't appear to be different..
