Brent, it's hard to describe, pics will tell a better story. The roof setup is sweet! Stay tuned
I've already arranged the sliding roof panels, with no destructive cutting / griding of the stock shed.
As for water, same issues here. I've used pop rivets instead of the supplied screws, and I have added lines of silicone in the roof / panel areas to be super sure.
My other idea is to add a curtain of that thick black builders splastic. The stuff you use for concreting, ponds etc. The curtain opening will be at the door. The stuff is 2m high, so it will do a great job of blocking rain and will make the inside even darker!
I also brought a $5.00 outdoor chair cover (green plastic stuff) from Go-Lo. Perfect fit for the G11 with scope on. For added peace of mind...
