Seeking advice on floor failure

Nevadan · 09-15-2016, 11:18 AM

Hello,
I have a 3 year old Jayflight ultralight X17z. In general I have been happy with it. I have used it moderately for 3 years. The floor has developed several "soft spots". Given time I'm sure I'll go through the floor. Has anyone had this problem? If so, how did you get it fixed? Thanks in advance for your help and advice.

If you are the original owner I would contact Jayco to see if any warranties apply. My 2016 came with a lifetime warranty on the roof, floor and frame. Have your VIN handy when you call.

A few related threads, and there are several others on the forum as well:

Call Jayco as others have mentioned. I do not know the floor warranty. However, you will not fall through the floor. It is a three layer OSB sandwich with about 2" of foam between the layers. You will be able to see the construction if you locate the large hole the 7 pin wire harness passes through.

Good Luck

Good links Crabman.

I have a soft spot at my door, and suspected a leak but haven't pulled up the vinyl to look yet. Plan was to have a pressure leak test first to ensure the envelope was solid before getting into a repair.

After reading through the links though, that sounds a lot like my issue since there is no obvious sign of water issues. (I'm still going to make sure it's not a leak though).

However, if it is simply a soft spot, and it bothers me enough, I have a couple of boxes of floating hardwood flooring left over from my house. Nice dark bamboo wood. Might consider just overlaying the whole thing with this flooring which is very strong and stable underfoot. Will have to take a good look at clearances for doors and drawers first. It would mean adding 1/4 round all the way through as well, but I think it would look pretty sharp, and two boxes won't add too much weight, especially if I remove the lino first.

The sandwich floor consist of 3/8 luan ply on top; 2x2-1/2 = 1-1/2 thick foam plus 1/8 luan on the bottom. So it is an 2" floor and will flex a bit over a 6 ft. span. With lighter RV frames they don't even use outriggers, except by wheel wells. The down side with this type of flooring is the screws they use in the cabinets to fasten to the floor, which can create squeaks. To solve this squeak, remove the screw and use glue or silicone on them.

dealer and I are waiting for jayco's decision, in my case there is a soft spot right at a seam were two sheet of sandwich floor meet, right in front of the sink. My dealer removed one of the grey tank to daiscover that they have nothing to work with to fix and or secure
the floor. They took picture and we are waiting for jayco's engineer to come with a way to fix this weak and poorly design floor

You can fall through. I Worked on this unit last year the owner fell through the bedroom floor. It was from a leak in the wall there the awning was bolted to the side at the roof line. Someone forgot to seal the bolts. Very hard (and costly) to repair these laminate floors and not have them be soft.

My guess is it's where the cut out in the foam for the water pipes to run through. The luan over that spot has water damage. I'd bet money on it. There are no seams. The styrofoam is one large front to back panel, with luan over it glued down. When it's right you can't feel any seems.

I've seen this before. Being right in front of the sink is the giveaway.

Thank you all very much!

My 2010 213EXP had a soft spot in the floor where there was a seam in the flooring. Of course, this was right at the entrance door to the trailer so it was a very high foot traffic area.

Since my 2010 is now out of warranty, and the soft spot getting worse, I took action.

I bought cut a piece of 5/8" plywood to width (about 21" wide) by a length of 48".

I also bought PL construction adhesive (for a caulking gun) and covered one entire side with this adhesive. I then put the board up in place and held it there with a automotive floor jack.

I then cut 2 pieces of 2x4 lumber 21" long each and covered one side of each with PL construction adhesive. I spaced them 24" apart.

Then I cut some metal angle to support the 2x4s and screwed them in to the cross members.

Once complete I sprayed everything with automotive under coating (in a spray paint can).

I allowed the adhesive to cure 48 hours. The floor is now rock solid. We went camping for 10 days straight about a week after fixing the floor and the floor has remained solid in that high traffic area.

I've attached a picture of what the underside of the trailer looks like now.

^^^ I think that`s the real issue with these floors, the lack of under support and not so much the flooring material itself. Your fix looks like it should do the trick.

Any chance your coming west to BC ?

I would like one of those.

i did not describe my situation properly, im a stupid frenchman you know lol....no water damage there we can clearly see the junction of two sheet of sandwich floor. and its not in the cupboard under the sink its where you stand in front of the sink...sorry for the confusing btw you can clearly see the seam through the vinyl floring, a nice straight line for the width of the trailer at that location

My dealership received the instruction about the proper way to fix that sandwich
its scary the procedure....4 pages, looks like the wont go from under to fix it, they remove the vinyl florring at the spot where the floor is sinking. approximatly 4x4 , they strip the first layer of luan, all the styrofoam, down to the luan at the very bottom, the will get to some crossmember, weld tube for reinforcing and build with plylam on top........heading to a catastrophy iam afraid . the trailer go in tuesday next week.....
