Need advice on repairing softspots in floor

[wannagetrdone]

I've got a 2005 palimino stampede. Bought it from close friend that fell on hard times a while ago, unfortunately the camper was neglected during this time. I have soft spots in the floor and from my understanding this is considered an ultralight trailer so it's sandwich material. I'm addressing a few suspect areas relaxing weatherstripping around the entry door etc. So here's where I'd like some direction. I'm thinking of pulling up the linoleum and letting it dry out. Use git rot on areas of concern kill any mold and recover with a floating floor like laminate after I can assure no future damage from existing problems. From what I've read this floor is basically pre-assembled, has aluminum supports and laid directly on the frame runner. Does the walls overlap the floor or if I cut out a rotted area how do I go about repairing underwater damage. It'd be easier if I just had to wreck to the wall but my ocd would get the best of me.

pretty sure that trailer uses a thin layer of flooring bonded to styrofoam insulation. You'd be wasting time trying to use git rot or other stuff. In lightweight units like that one, they save weight by spacing out the floor supports underneath further than normal. I would just buy some angle iron and put in a couple more supports under it. Weld them in at each end, or use self tapping metal screws

Well that figures, seems to be about the only places my rot is.

If the rot goes to the walls it becomes a major project but possible. I'm sure there are YouTube videos that will give you direction.

You need to get the subfloor stable to install laminate over it. IF you have failed foam core and sheet rot, it needs to be replaced with new material.

Typically, walls are installed over the floor deck but that may not be true with all.
