Lots of great information and resources on this site, looking forward to sharing my build with everyone!
My name is Jason, finishing grad school soon and looking forward to some extended traveling. Basing my design off of Taxa's Tiger Moth trailer

My initial questions:
How have others supported their build when overhanging their frame (I have access to a welding shop, and will be tightening up my trailer this weekend and adding some additional supports)
I've sourced a great local marine plywood supplier with an excellent selection of materials. Intend on doing SIP walls, but unsure what dimensions make most sense. 1/4" ply 1" foam w sticks 1/4" ply. Do I need 1/4" ply on both surfaces, can I get away with 1/8", which face would you put the thinner ply?
Having a hard time finalizing the height dimensions, the Tiger Moth trailer has a slanted roof design. One of the reasons I was drawn to this layout was the ability to sit up inside the trailer. I'm 6', now I don't need to stand up inside my trailer (galley style kitchen and no bathroom facilities) but need the bench/bed to be min. 18" for storage/fridge. Visualizing available headroom has been difficult, currently have designs with 6' at the entryway tapering down to about 5'. The manufacturer has the interior height listed at 4'10". What do you feel is a comfortable clearance while in a seated position?
Those are my some of the questions I'm working through currently, appreciate your feedback and your recommendations!
