Sharon,
I'm happy to see that you worked out the separation of the propane and electrical. Your "kitchen" is really looking fantastic! I really like the way you constructed your doors.
As far as CPES making pine less resistant to impact, I can tell you from experience that it is a fact. In the front of my teardrop I have a "roll pan" constructed to a small radius. Rather than trying to fabricate the part below the floor out of plywood rinbs and skin, I used solid pine and planed it to the radius. I chose the pine for its light weight and easy cutting. After it was shaped, I coated it with 2 coats of CPES, and it became quite solid.
Keep up the good work. Maybe some day an interloper from Texas will show up to IRG so I can see your TTT.
Tom
