Quick C channel question

Hi all,

A quick question. I am currently taking out a section of the rear bathroom floor all is going as well as expected. I was surprised to find, from the battery box to past the curve of the corner and likewise on the opposite side there is no c channel for the floor to slip into. There is only the one that sits on top is this correct? I thought the C channel is where the strength came from and provided some water protection to the edge.

Thanks in advance,

Tony S

Rear flooring sheet end is clamped between the single-C-channel and frame cross member..

Two gaps in the rear single-C-channel for the Battery locker and water heater...

The "double-C-channel" begins at the end-cap seam to only exist on the straight line wall runs.

EDIT - The shell is stiff enough on its own to be said to 'hold the floor/frame up". The side double-C-channel helps spider web connect all the outriggers and keep the floor from deforming. The shell endcap single-C-channel has the main ladder frame to tie into with a much shorter span, the rear has to flex if/when the L/R back frame bottoms out.

It is a 1973 Tradewind, sorry about that. Thanks for the quick responses back, it keeps me rolling. I am afraid to stop or I might not keep going. Not really but I know it is a long road.

Many Thanks

yeah, there was none on mine, either. short little chunk of it, just aft of the wheel well on the street side. (corresponding spot on the curb side is where the battery box is, so...none there.). It doesn't appear to to me to serve much of a purpose.
