Using pourable epoxy on floor soft spots

Even though the unit is a 2021, it was purchased in 2020 and is out of warranty. I have contacted the manufactured several times and they are not getting back to me.

The soft spots are not numerous - and I know the proper repair is to cut out the osb and repair it. Given that I only have a few spots - I thought I might get away with an epoxy repair.

Given the location of the spots - its really going to take some work to replace the wood where the issues are. The door will have to come out - amongst some other furniture and wall panels.

Wow, they have drastically shortened the warranties :M sorry to here this.

Back a few yrs ago, there were often 2 or 3 yr warranties on most TTs.

The problem with a quick fix, is the damage when it comes to water is typically a lot more extensive, the soft spots are a symptom of long term leaks that happened without your knowledge until you start noticing a soft spot.

Epoxy by itself is going to create a temporary at best hard inflexible bridge to the adjacent OSB which will still flex. The already compromised OSB around the epoxy will simply continue deteriorating.

OSB is pretty much all water based glue with large flecks of wood chips and the whole thing is pressed together under high pressure until the glue sets. All it takes is a little moisture to wick into the wood strands and it all falls apart. OSB and MDF doesn't glue well if you are looking for strength.

I didn't check your model number, if it is a "lite" or Lightweight trailer, you may have a double whammy.. Typically to save weight, the manufacturers for "lite" models use much thinner 1/4" subfloor which starts to weaken and sag in high traffic areas.. Basically the floor strength depends on the foam insulation and that breaks down each time it is walked on and flexed.
