Position the Plumbing and Narrow the Wheel Well

I need a shower and we also want to keep the living space as open as possible so we need to crowd the bathroom.  Before when we checked the fit, there is very little room between the toilet and the wheel wheel. 

 As new plywood is cut for a floor, the size and shape of the trailer can tweak a little bit.  Now our 1955 Flying Cloud final size of the Airstream is defined by the floor attached to the chassis.  With the wheel wells attached between the plywood and the frame, the bathroom plumbing needed to be double checked. 

Axle and tires on, the chassis is flipped over.

Great news!  The shell still fits on the floor/frame!

Next the plumbing parts are laid out in their approximate positions.

The mock-up wall is brought back into our trailer to check the fit.

With the new axle and tire in place, we could check that all would still fit, and as expected the wheel well needed to be slightly adjusted.
