I have completed my canopy portion of this build. I installed my trim to the front and the rear of the canopy, also using clear silicone and two #6 screws for the rear trim. I used .032 for the rear trim in hopes that it would provide a stiffer assembly. I used commercial grade short rivets from Lowes to attach my canopy to the slide rails. Everything works wellm but I am not happy with the slide system, but will make do.
