flooring repairs too!

I have ripped up rotted subfloor in the front half (and now bathroom) of my 77 overlander. Pardon the rookie question, but how critical is it that the flooring is up in the channel along the bottom of the wall? I didn't cut my front piece perfectly and it isn't up under there that good. Also I had to cut the original bolts that were used to hold the subfloor to the frame and I planned to just use self tapping screws to reattach the new subfloor to the frame? Is that ok to do that?

It could be very critical. The upper aluminum structure ties to the steel frame through the plywood subfloor that sits underneath that c channel. The c channel has to be bolted through to the frame as well as bolted into the plywood to form a rigid box otherwise it will flex and you will see interior rivets start to pop.

Thanks for that info, I'm a newbie and that really helps plan what needs to be attempted first. Do you know where I can find a diagram of the frame with dimension data on an older Airstream?
