So sorry - I do not remember what is was for this door. But most cargo doors that I see now on eBay indicate that the stated size is the "cut-out" dimension and NOT the size of the actual door. I should have measured when I was down at my trailer but didn't think about it. I should have held a tape measure up against it for the pictures.... And in this case - size does matter.
If you look at the outside pictures, you'll see that the door frame butts up against the side marker light in the lower left corner. Any further to the rear of the camper and it will interfere with the light. Then if you look at the inside picture you'll see that if you try any further to the front of the camper, the frame will actually interfere with the interior back wall of the shower. And you have the same problems with height. The door any lower will once again run into the side marker light. Any higher and it runs into the wooden shelf area that runs along the back bunk. As it is, when I made the cut, I removed a section of the 1"x1" cleat that is made to support that wood. It still has the cleats on the long edges and that part of the camper it the most inaccessible part. My daughter puts her dolls or stuffed animals there when she is sleeping so I'm not worried about it collapsing or anything.
All in all, I got VERY lucky when I purchased this door. I made a template of the cut out and taped it to the outside of the camper. I drilled a pilot hole through the wall and then used that to do measurements on the inside to see what the cutout would interfere with. That's how I knew I needed to butt up against the marker light. Then I adjusted the template, measured about 10 more times, said a prayer, and went to work with the saber saw. It cut through the wall like a hot knife through butter so I had to be careful it didn't get away from me.
All in all, the best mod I've ever done!
