The saga of my junk rig.....I need suggestions....

If the floor is getting wet, you need to find where it is coming in. I would suggest either the roof above the door or the door itself is wicking water into the frame and getting the floor wet. I had that happen one time. I agree,take the awning off and just put bolts with silicone on them.Check all of your caulking on the roof and sides and redo as neccessary.When not in use,cover the whole unit with a tarp.
