5x8 tear .
So how much room do i need to leave above and around the tires if i leave the tires inside?
Right now the tires are sticking up a 1/2 " above the frame no weight on the trailer and i'm planing on building lightweight 1/2"ply for floor , walls and cabinets, door skins or 1/8' baltic birch fot ceiling and roof .
No off road driving most camping will be Georgia state parks very few dirt roads.
I know tires inside are in the way but they would only be in 6" on each side an i don't sleep on the side of the bed cindy and i tend to sleep in the middle so i don;t see that this would be too big of a problem once you nail your shins a few times you will to keep them out of the way
