depth

As plywood is a layered product is it just on the outside layer, or does it run the depth of the wood? If it is a complete split of all of the layers (and I would bet it is not), and still in warr then dealer it goes. If it is just a layer I doubt they would bother with it, as it may well be the grade of plywood they use and have little structural significance. You may consider glue and screw another sheet of half inch on both sides of the rails, but I like to reinforce everything.

Regardless, seeing "raw" plywood exposed that looks like non treated or external grade I would seal it with some product or another.....

It does run the depth of the wood, the dark you can see it whatever is on top of the wood, feels like underside of carpet??

Have you figured what/where is above the crack when you’re inside?

Looks like it is inside a basement or other enclosed area and not open to weather. Depending on what has to be removed/ disassembled to fix it, might be easier to seal crack and laminate a piece the entire size of the space between the aluminum frame pieces for strength.

In the first photo it appears that the aluminum framework is bent downward at the crack. Something very heavy being dropped at that spot?

Plywood has layers that run opposing directions, a crack like that should be impossible without great force.
Are we seeing light thru the crack?

The second photo looks similar to what you would expect on the underside of A/C grade (one side good) plywood.

Aluminum is not bent, just flash of camera that makes it appear that way. No light seen through crack.

Just another example where the manufacturer's try to save as much money as the can by using the cheapest materials as they can. I have a TH with soft spots in the floor you can feel just walking across them. I haven't loaded my motorcycle in it yet, sure hope it holds up when I do. As already stated, I think I would let the dealer fix it or add some plywood to reinforce it. Good luck.

How thick is the wood and is it plywood?

It would be odd for plywood (multiple layers of wood with cross-stacked grained layers) to have a crack go through all the layers to where you could see carpeting above.

What is directly above the crack on the inside?

Looks like thin plywood to me. Hard to tell what is above it. It’s black and feels coarse like what you would think would be underside of carpet, but hard to tell??

The black you see in the crack is the adhesive on the next layer of wood. IMO you have nothing to worry about. If you go to a lumber yard and examine the plywood panels you will see most of them with the same condition. Plywood without imperfections on both sides is expensive and not used for flooring. The plywood in your RV is at least 1/2 inch thick, made from 5 layers of wood, glued together with heat and pressure.

Plywood is made in various thickness from 1/8" to 3" thickness. The number of plies, which is always odd, depends on the thickness and grade of the sheet. Sub-floors are at least 3/4" thick, the thickness depending on the distance between floor joists. Plywood for flooring applications is often tongue and groove. This prevents one board from moving up or down relative to its neighbor, providing a solid-feeling floor when the joints do not lie over joists. T&G plywood is usually found in the 1/2" to 1" range.

I agree with Scrapper. That appears to be the outer ply of cdx plywood or some such, which is made with a low grade ply on the bottom side.

It is still under factory warranty, should I leave it alone, or take to dealer?

How deep is the crack and how thick is the plywood? What sits on top of the plywood in this location? That info would help answer your question.

Me it would be back to the dealer. Others might try and fix it but I would take it back and have them fix it. Just MHO.

Plywood is maybe 1/4”, underside of flooring sits on top

It never hurts to ask, but I expect they will tell you this is CDX sheeting and is normal for this product. It apparently does support a lot of weight and is not an appearance issue.

Thanks and I know we keep asking about the thickness of the wood and what's on top but these are really important questions.

One, if it is truly only 1/4" thick plywood, I would have much concern.
1/4" plywood isn't thick enough for a sub-floor and certainly not across the spans (aluminum framing) we see in the photo. The only thin wood material I've ever seen for flooring was that which is bonded to a foam core top and bottom. Not an ideal floor but comes in at about 1-1/2" to 2" thick. Typical plywood floors are 1/2"-3/4" not 1/4"

Two, when asked what is on top of the crack... we are referring to what is actually inside the rig at that spot? A bed? A dresser? The bathroom?

If your floor is 1/4" thick and you can actually touch the underside of the carpeting through the crack, you have what I'd describe as, MAJOR issues.

We are simply trying to get a good grip on what is actually going on with your floor.
