3023 Frame Properties

Greetings colleagues,

Can anyone give me the dimensions and thickness of the 3023 frame? What would be even better would be a complete dimensioned shop drawing of the frame.

I'm prohibited from storing a camper outside my house, but a 3023 will just fit in one side of the garage if I make a detachable tongue to make the frame (during storage) even with the front of the cabin. This requires a rational engineering analysis of the dynamic loads to design a set of splice brackets (probably "L" or "U" sections to fit over the frame) and torque specs for the grade-8 bolts.

I'd love the convenience of the spring-pin design, but the 2' swing-away tongue doesn't shorten the 3023 sufficiently. I need to get to 19'-3" overall length. And cutting the tongue further back means the triangular piece is too big to "nest" against the unit, making the swing-away design impractical.

Obviously, this voids the frame warranty.

Thanks.
