Wentzzee,
Can you build the body bigger than the frame? Sure.
The one thing I would look at when doing this is how the body is attached to the frame. Overhanging the frame on all sides could be a problem - you don't want the situation where the rigid body is supported on a trampoline floor. It is the vertical parts of a teardrop body (sides, front, bulkhead) that give it strength, not the floor.
There are several ways round this potential problem:
- A normal galley/cabin bulkhead will connect from the frame to the sides, so that's the bigger half of the problem solved.
- It would be nice to connect the bottom of the front wall to the frame, as that would give a second point of attachment. Alternatively:
- If the floor consists of some framing under a sheet of ply, and not just the ply on its own, it should be able to connect the body sides to the frame. You might want to use framing 1-1/2" deep, rather than 3/4", to do this.
Is that clear as mud?
