As I continue the planning for my new insert, I contacted Travis about their new flush model. A couple of months ago, a dealer informed me that The FPX 33 aka Lopi Declaration aka Avalon Perfect Fit would be going to a single door model for the next season. He e-mailed me the dimensions page of the new manual. Here it is copy and pasted into a paint document with last year's model. Note that it is indeed a single door and the firebox is smaller. I'm glad I asked because I might need to buy last year's model now. A heads up for those of you in the same situation. The guy from Travis said there's about 140 left. After that, they're gone.
