No. The floor is attached to the frame, and not really attached to the trailer, except for some little screws in the floor channel. The full attachment is the outriggers have bolts through the ends, through the floor, and into the bows (upright aluminum frame parts for the shell). There are also many self-tapping screws that hold the floor and frame together. If you really, really wanted to, you could probably support the trailer and floor, and cut out each frame section, pull it out, replace it, and weld it back to everything, then repeat on the other side. That's a lot or work, and magnifies the possibility of a fire when you start welding near that 35 year old plywood in the floor.
