Have been working on my hatch. I have the inside layer of plywood installed. The wiring and blocking is finished. Now I am ready to put on the outside layers of plywood.
Here is the hatch after I removed it from the trailer.

This is after I applied the inside layer of plywood.

Here it is on it's side beside my house. This is a BIG hatch. It is 78 inches wide.

Back on the trailer after the inside layer of plywood was installed.

Blocking for the gas struts.

Wiring completed in the hatch.

Now on the to the outside layers of plywood.
