I have decided to go to the outside of the trailer for the next phase of work.
Shown below is a photo of the finished installation of the exterior front curve at the front of the roof.
This panel is 3/16" bendy plywood.
The curve is about a 15" radius.
I used 1-1/4" #18 brads to hold down the plywood while the thickened epoxy drys.
I nailed the brads with my new air compressor and nailer.
The air nailer is so much better than an electric nailer.
This roof panel, of course, needs to be trimmed, sanded, & epoxyed.
The hole is for the installation of the Fantastic Vent.
Shown below is a photo of the finished installation of the exterior rear curve at the rear of the roof.
The hole & the shelf are for installation of the air conditioneer.
Next I will be working on the middle three 1/4" panels for the rest of the roof.
