Well this weekend I've been forced into installing a heated tile floor in the basement bathroom so no physical progress on the trailer. Luckily I'm off this week and the tiling is almost done so I should get some done this week. What I was able to do while recovering from being bent over on my knees all day was make a basic sketchup model of the trailer so y'all will know just what the heck I've been talking about. The dimensions aren't all perfect for the placement of equipment but it will give you an idea what the plan is. I'm attaching screenshots and if possible will attach the sketchup file.

Basic side view, here you can see the front aerodynamic cowling which will house propane tanks and batteries and double as unheated storage.

In these two shots you can see the fold down couches which together make into the bed.

The other pic shows where all the mechanicals will be built into.

Update:

I started putting the walls together to give myself an easier time than working with the panels. I had set up stands to work on each panel but reaching the center was a pain so I decided to put the framing together.

I started working on the truss design and I think they will work out great. The diagonal braces which will be under every other truss (4' OC) will be hidden in the cabinets. Trusses will be 2' OC.

My plan is now to skin with .032" 5052 aluminum sheet which will be adhered with VHB tape to strips of the same material screwed through into the framing. I wouldn't trust the VHB to hold directly to the foam so this is the plan I came up with. VHB is quite expensive but after a test run using aluminum fascia material and roofing screws, i couldn't stand the look of hundreds of fasteners. I paid $286 CDN for 3X 36 yard rolls of 1" wide 5952 tape on amazon and for that specific tape it's cheap. It's almost like amazon isn't aware of how much it's worth.

I will continue foaming the frame once the roof structure is in place and the front wall is framed. The extra rigidity should make installing the foam easier.

Anyway, I know you're all just here for the pics so here you go

As heavy as your framing is. I don't think your going to need those knee braces. If your running rafters at the 2' centers.
Here is my build.

In all honesty you're probably right, they are mostly to keep the walls square with the ceiling since there won't be a floor until the cabin is installed onto the trailer. Also I wanted something rigid to prevent racking since the rear of the camper is actually a door and less rigid than a framed wall. The 16" deep by 16" tall full length cabinets in the top corners will completely hide them anyway so why not.
