I've got the same issue- toy hauler trailers are insane $$$. $80k for a 5th wheel big enough to handle a jeep? Crazy.
I'm planning on building this in 2 pieces: A sleeper area on top of the gooseneck, and a 10' box on the front of the trailer for a kitchen/shower/toilet/ ect. I want the RV box to be removable in case I need more deck space for a project, and still have a usable sleeper.
So, i've got a footprint of 8' wide x 9' long to work with, and a couple of goals:
I can push the length to 10' by way of a 45 degree corner on the bottom (just like the weekender).
Max height is 52"- I want the max overall height to be 11', the top of the gooseneck is 80"
Rear entrance
No need for a rear galley- I'll build a simple galley in between the gooseneck uprights
sleep 4 people
I think my biggest concern is supporting the roof- we get snow here in utah.
I'm not really sure on inside layout yet, i'm thinking it might be easier to build the shell then see what fits
