Sure, I am waiting for Bruce to give me his recommendations. However, as a general rule, I believe that 15 or 20 amps would be appropriate for most of the 12V circuits. The AC side will have a 30 amp for me and the GFIC will do most of the work anyway. I will update drawing(s) when I am more sure of the appropriate fuse/circuit breaker sizes and wire gage size.

There's two ways to size everything: design the wires and fuses around the actual loads, or we can make some general assumptions which I did here:.

Since everyone does their trailers differently, I'd lean towards some general assumptions, meaning worst case, very conservative. Does that sound okay to everyone?
Also, here's a list of wire sizes and ampacity for THHN 75 & 90 degree wire per NEC-310-16, which is a close to generic as we'll get. YMMV. As always, read the package for your actual product.
#18 - 14A
#16 - 18A
#12 - 25A
#10 - 35A
#8 - 50A
#6 - 65A

P.S. You may have noticed I edited this post. My diagram is pretty general (after looking at it again with an Adobe reader that works) so I changed the post to reflect that. I also fixed the link.
