Cut an access panel in the floor or find another way?

I'm surprised there isn't some access panel hidden away under there. Not only good to access to the transmission, but also good for the rear of the engine too.

I'm working a big plan to gut most of my interior and build my own custom bunk storage and setup. I want the bed area to pull triple duty as an office desk and a bathroom (with shower). All in a 48" sleeper! I've already got a basic layout, just need to work on the specifics of how the bed will move and what kind of supports I'll need and where. HOWEVER, none of this will happen until AFTER I pay for an inframe.
