Soft floor between floor beams in 2701SS?? :( Anybody Reinforce??

I know alot of people on here have come upon the spongy floor between beam issues in there trailers. but I have not seen too many solutions. People have talked about adding more braces using 3/8" ply and/or welding additional beams with metal or wood, But cant find the threads. I have a 08' Rockwood 2701SS and from the front bed all the way back to the bathroom its spongy between the 24"?? beams ( i havent measured yet). I looked underneath and it has some kind of tyvek paper under the floor them the beams on the frame. I would like to weld some add'l beams either 2x4 or 2x2 but I dont want to add too much weight. also maybe I should add some plywood if I can between my new beams and the floor to again add stability. Let me know what you guys have done to fix it and what worked and what didnt. Thanks again

I am going to post pics today to show you guys the span of the beams underneath the floor, to get a better understanding.

Can you actually see the floor from underneath the camper? I am unfamiliar with the model you have. Are there not the gray and black water tanks underneath?

the tanks are back there towards the rear of the camper. Yes you can see the underside of the floor that has a vapor barrier on it. This is not a 5er style when the floor is all enclosed. My unit you can see the vapor barrier and the floor beams and some trailer wiring running through the beams. all from under the trailer.

You are lucky then. The pics will be interesting, but it doesn't sound like you should have any problem beefing up the floor.
Too bad that the company would build such weak floors though. That is the last place they should be scrimping.

PICS: these are the underbelly of my trailer. As you can see you can see the floor above the beams underneath. The factory made this frame with this big of a span. and I believe 1/4" luan sandwiched with some styrofoam. Its the only thing that bums me out about this trailer is the floor. So if anyones dealt with these floors and what they did , Let me know. thx.
hopefully this weekend I will go get some steel and do some bracin'

That is quite a span between those supports!
But, it looks like you shouldn't have too much trouble adding extra supports. Not sure if you can get the "Z" bars they use, but you should be able to find some lightweight 'C' channels, which will work just as good.
Good luck.

Ya , It is a BIG span. Its really the only disappointment I have with this trailer. I have to find some either 2x4 or 2x2 steel 1/8" thick stock to weld in there ( I think 1/4 inch thick stock will be too heavy) Also I wanted to either put them parallel with the other beams or make some other braced pattern either "H" pattern or "X" pattern underneath but i dont want to add too much weight because I have to do 3 or possibly 4 bays. less cuts the better. Anyways has anyone done this bracing on there trailer? with wood or metal?

thx again,
