91 Warrior spongy floor

[twodog]

I  have the normal spongy floor in my 91 Warrior  I removed the carped, and there doesn't seem to be any rot that is visible.  I was wondering if anyone has had any success drilling holes in a 6 inch grid pattern and injecting epoxy .    I have seen a couple of videos on you tube on this, but just not sure how successful this is.     Thanks for any help

Get underneath the coach and look up to see where the wood is punky

Warrior floor will never be rock solid, IMO: it has a light sheet-metal underbelly welded between the frame rails, with foam board on top, and a final layer of thin ply. I think it's reasonable to expect some flex. Long as the sheet metal layer is intact and not loose, you should be okay.

My '93 Itasca Spirit (same as Warrior) has the spongy floor issue. If I look underneath it is in great condition but still feels kinda soggy when you walk near the stove / bathroom door area (rear bath floor plan). I've thought about adding some stiffening underneath between the frame rails. Maybe some angle iron that is notched to sit on top of the frame on each side. One day I'll find the time to give it a try!

I think I remember someone drilling a grid on the floor and epoxying in wood pegs (dowels). Said it make a big differance

 Interesting topic. I'm 98% sure I have all my leaks stopped. Next to address was going to be the floor. I see where a few mention a bit of spongy areas but what seems to be a pretty solid floor. I've been under mine and have poked around and it seems pretty solid. I suppose I'll find out before long. I'm putting waterproof laminate flooring down in our bedroom/bathroom and I hope to have enough left over and pieces to do the RV.

As previously mentioned, the "sponginess" is a result of a lack of support for the floor.  I did the epoxy process and it works wonders.

I'm thinking about the epoxy route.     just don't know how deep to drill.    does anyone know?

My floor was intact and not rotted in anyway.  It did have some flex when walking on it.   I looked all the options over and added a cross brace underneath in the middle of the flex area.  Worked well.
