So I had to scrap a bunch of work I'd previously done, I realized I'd stretched the cabin too far forward in relation to the vehicle. I spent today loading the trailer frame into CAD, along with determining the right size for the wheel wells and sketching out the under-floor storage. Looking at the original profile, I really appreciated how much time Mike had put into saving plywood, when my stretched idea threw that out the window and wasted a significant amount.
I thought about going lower on the under-bed storage boxes, but my driveway has a rather dramatic convex lip to it when I get up to the street, I don't want to take it out for the first time and lose all of our extra blankets or find it high-centered.
The profile in the pic is the original Weekender, I may raise the rear galley roofline a bit, depending on how the cabinets and space claims work out.

Technical challenges and design choices ahead:
1) 3-door galley hatch or deal with the complex shape and the head-banging potential? My wife isn't the strongest, nor the tallest, so I have to remember to make it easy for her to use and not just me.
2) Front storage, I want to add extra storage by making the front vertical panel extend all the way down to the trailer tongue, inset maybe 6" from each sidewall, so that we don't have wasted space behind the tongue box. I also need to determine how to handle the air contioner, with the current nose design, the AC unit may stick over the bed about 3" when in the retracted position, if I continue with my plan to have a fully retracting AC.
3) Trolley top? Losing 2" of headroom to the raised floor doesn't seem like much, but my wife's insisting we plan on a traverse bunk for a future addition...
