Sorry Birdstrike,
I took some photos of the back deck I put in. Let me know if you get them. I used angle aluminum as "joists" then laid the .100 sheet down. You can look on Xpress's sight for a before picture. 16' tunnel hull flat bottom with the corner pods. My deck and all of the angle cost a little over $200 the best I can remember. If you need more pictures or additional detail let me know.
Chris
