I have a floor in my 7 year old trailer that is soft in the busiest part of the trailer. You feel the support floorboard, but it is soft on both sides of it. The floor in that spot creaks like an old house. There is no evidence of water.Throw rugs over the place almost always stops the creaking and noises. What do you think I should do?

Check your roof, windows, etc. for leaks. Get them sealed before you repair the floor.There's no point working on the floor if you still have a leak.Consider a pressure test by a RV repair shop, it will find any small leak.

Is it an ultra-light model? It may have a foam core floor that is breaking down

What Make and model is the trailer? Where is the soft spot? Does the floor have carpet or vinyl on it. If vinyl you can tap the floor with the handle end of a screw driver and see if you here a difference in the sound of the soft area versus what doesn't feel soft. If bad will have a soft thud sound verses a sharp tap sound. If sound is different then worth further investigation.

What should you do? Well, that depends. Are you going to keep it, or trade it in? Put your carpet over it, and trade it in?Sell it the way it is?Or lift the vinyl up, then the OSB that is likely rotten over twice what you think it it. Replace it back to solid floor joists that have no rot, then cut the vinyl back to a logical spot and put in a patch of flooring boards with nice trim on the sides to cover the edges. Or do the entire job with new plywood as much as you can, and replace all the flooring.So..what will you do?

You have not provided enough information. If it is a ultralight with the foam core floor or a conventional trailer?
