Building manual for when you don't know what you don't know

We're a pretty handy couple and have about 75% of our Grumman 2 trailer designed in CAD. However, we keep realizing there's a lot we don't know, then spend a few hours lurking in the forum for answers. So I'd REALLY like to get a construction guide so we don't forget some critical part of the trailer or that we're not re-inventing the wheel in how we do things (unless it's intentional).
I'm talking about:
-The best ways to attach walls to the floor/trailer.
-Water tank location & design
-Complexity of DIY doors
-What to use for aluminum trims at intersection of walls & roof.
-Finishing details
-Sealing ideas
Consequently, I want to buy a construction manual, and so far the top contender is the Camping Classics Teardrop Build Manual, but since it's woody-based, I'm wondering if there's something similar for those of us doing aluminum skins, or if the Camping Classics one is versatile enough that we can get answers to our questions there.
Thanks for your input!!!
