Hi Michael Quick, welcome to Permies,
What would be the best way to anchor them together? Im lost.
I'm lost too??? "anchor them?" Them what? I understand 25' long, but 8' peak and 6' back is a bit confusing. I am not sure if your design is plausible (or appropriate.) for a wood drying shed. What do you plan to frame it with?
Wish I could be of more help,
j
