Slideout floor replacement

[LADY_JANE]

Just discovered about 2" of rot along the entire edge of the bedroom slideout floor--appears to be coming in from exterior trim not being caulked and allowing water to enter and sit on the frame the floor rests on. What a stupid design.
Anyway, has anyone had experience repairing something like this? Can the rot be cut out and filled in with something or does the entire floor have to be replaced?
DIY or is this best left to the pros?
Thanks.

In my case the slide out drive rail was bolted directly to the bottom of the floor. They all seem to be a bit different though. I attached 2x6's as stilts to the outer edge so the 2x6's supported the slide from the ground. I unbolted the slide out rail from the floor then retracted it back in. Then I had easy access to the floor to remove it.

Have to do the same thing. Question: why do you have to support the floor or disconnect the drive unit? Is the plywood connected to it? Or, is the plywood connected to a separate "joist system"? I can't afford $3k. I will look at the videos posted also.

to do it. I took measurements and bought 1" exterior plywood and pretreated it with 3 coats of poly. Ran slide out and disconnected the drive unit. Supported slide outs with 2x4s . Tore out bad piece and inserted new floor and reattached drive unit and we were finished in 3 hrs. Total cost was $60 for plywood and $10 for 2x4's and $10 for poly.
So for a total of $80 was better than new.

Where do these RV repair shops come up with these insane prices? I just can't believe the estimates for some of the things I've seen. One wanted to charge me $8,000.00 to paint and replace the decals on the front cap on my 5th wheel. I got it done for $1500.00 which was still too high but I couldn't find a place big enough to get it into.

Take a look at these videos I found. I did my bedroom slide not too long ago.

So, did you determine where the leak was? And what did you do about it?

Thank you!

it does take time but i did mine this winter I used a piece of 1 inch thick marine grade plywood. I just made stilts to hold the room up in the air and slipped the old floor out and the new one in there. I also did have to change some rotten studding along where the floor meets the bottom of walls.

The OEM floor on my slide out is a super heavy duty epoxy impregnated product. It is black and weights a ton. The trailer manufactures do this to ovoid using the plastic underbelly wrap on the slide. I think that you would need to do the at least the same level of protection.

In my case I used 2 layers of 1/2" plywood glued and screwed together after being sealed as the original floor was 1" thick OSB type material. I also cut a piece of FRP and glued it to the bottom (the part that gets exposed with the slide out). I looked at keeping the original floor and treating it with a marine type epoxy (I can't recall the name)that penetrates the wood and hardens it. In the end I opted to remove the slide floor and replace it. Probably the hardest part was finding all the screws to remove the old floor.

Also as a note, I did it without removing the slide. I extended it and attached 2 2x6's to the sides to support it.

The product you mentioned is sold by the "Rot Doctor". They sell a variety of epoxy products. I have used the two part penetrating epoxy to coat new wood and it is an excellent product. I dont know if it would help the op but that job does not sound like fun.
