And I thought my frame was strong.
I think you beat me!
I like the shape of your tear. I think I'll try and get closer to your shape. I'm gonna keep the vertical front to maximize interior floor space but I like tucking in the rear end a bit. Here's my current mock up:
Where the two horizontal blue tape stripes end will be the cabin's rear bulkhead with about a 14 inch storage space with a door on each side. I'll have a 20 gallon water tank , the battery, and room for chairs and other stuff so I don't have to store/carry stuff in the cabin when traveling. The galley will have a small r/v range/oven and a 3 way reefer (on hand) installed.
What is "lattice strip" and where did you get it. I used sched 125 pvc pipe but I like your technique for marking the curve with spray paint.
Looking good.
Cheers,
Gus
