The cord is for reference where the floor is soft and spongy.

I'd venture a guess the floor isn't rotting, its compressing. That spot see lots of concentrated weight leaving and entering the RV. Below the flooring cover is a layer of not very thick OSD plywood, very light but not as strong as laminated ply. It flexs over time and below it is 3-4" of molded styro-foam. Its this layer that will compress and stay spongy. The flooring covers then have little support. There is alum or steel tubing running both directions but some times too far apart. The fix can be to insert and area with the orginal floor cover, osd and foam with luan and fiberglass mount on the bottom. This common in front of stoves and sinks also. I think your talking capable rv dealer or factory. I also think about a reinforced floorplate like diamond covered aluminum plate cut to suit and secured. Just an idea.

Can't tell without removing the threshold. My previous rig had a spot just to the left of the threshold. Water was running down the side and under the threshold because there was no sealant under it. Used polyurethane to seal. Found it when I lifted up the vinyl because I was going to remove the carpet and install Allure. Damage was just beginning. You will have to remove the threshold and look under the floor covering to be sure.

x's 2 You will have to pull the threshold, looks like the corners have been repaired already. Water could be just coming in under it just like at your home if it's not sealed correctly...

I would think that is one piece by the way these trailers are made. I really couldn't say, unless you can cut it out and then reseal it at the edges. More then likely the floor would have to be repaired under it to from water damage. It might be easier to remove the whole door jam. I think the harder part will be repairing the floor. In the marine Ind. they use a resin for dry rot. you inject it and it will turn harder then the wood, you might want to look at that option, just a thought. Good luck on the repair..

Thanks. I will try. If all else fails i will try a piece of diamond plate aluminum and seal around the door and threshold. Any other suggestions are welcome.

I just got through doing a repair on my Puma. I found a soft spot going in the front door to the right. I replaced the whole section at the door, back towards the front, even into the storage compartment. I have checked everything around the door, resealed, hope that fixed it.

When I replaced my flooring it was the 3/4 OSB. I had to cut some 2x4s down to 2 1/2 inches to install under the flooring. I just attached those to the others, then installed my flooring on top. Just hoping I don't have to do it anymore. Hope yours works out okay.

Mine has luan on the bottom then 2 inch styrofoam then another layer of luan on top then the floor. Got a plan. Gonna get some 2x6's and put an aluminum plate on bottom for support. Drop it in the empty spot, brace it up them put a layer of luan down then drop the flooring back down.

Sounds like a good repair. I had to drink several cups of coffee and look at mine before I started. I think I even went over it in my sleep a night or two.

Remove the 3 screws and the threshold should slide out with a little tpping side ways.

Is there an exterior power plug near there? When I first got my previous TT I had a leak through the power plug. Removed the cover and sealed with chaulk. Good luck.
