I did have an open floor on the tent camper. But I thought I wouldn't really be able to easily seal out water.
I kept the additional framing but removed the various width 1 x's. There is always use for some primed and already painted boards.
Instead I opted for a tradional floor but with all the framing went with 5/8" instead of 3/4". The trailer is only 6' long and has plenty of support.
Paddy has her eye on the new project.
Wall go up next!
