Hi RCICH
Great timing, I was about to start the glueing process on my hatch.
I read through the the book and there was no indication that the authors stitched the hatch in place. However, I plan on stitching the corners in place (two on each side). When I was lining this up I had to drill holes in both the hatch and through the trailer -> the holes did not align well.
Just my 2 cents, and I’m off to do it. I will let you know how it goes once it is cured (will be this weekend).
Best wishes for your build,
joe
