Am I crazy, or is this not 5/8" plywood flooring?

[Yillbs]

My RV is supposed to have 5/8" flooring, I noticed lately ( it's a new unit ) that the floor was a bit spongy. So, I measured the plywood... Am I missing something here or did I get duped.

Actual Plywood Thickness and Size

The actual thickness of plywood is often thinner than the nominal thickness shown at the lumber yard. 3/4" plywood is usually 21/32" thick.

You think 5/8" plywood should be smaller than half an inch? I don't understand your response.

I was just giving you the standard sizes, all of which are smaller than nominal.

Also, it appears to me that your tape measure may not actually be at the bottom of the plywood, but it's hard to tell for sure from the photo.

So, I just replied with the standard sizes and you can see if you were given less than promised.

I've attached a mil tool that measures considerably more accurately than my tape measurer. Their are two images. One is the floor thickness with the laminate on top, the second is the thickness of the laminate by itself. The entire thing is 0.56 inches, the floor is 0.049 inches thick, this means the actual size of the floor is 0.49 inches, which would be in line with 1/2 in thick plywood. I have tons of it at my house, and when I measure it, it's between 0.48 inches, and 0.51 inches, so I'm confident this is just half inch thick plywood. I guess my question is, is this normal to market something and then you get this. Surely the variation in sizes isn't THIS much?

Seems a bit thin to me. The more I shop, the more I'm disappointed with the available quality seemingly from all makes. The quality of the dealers isn't so great either in my experience so far.

The easy solution to this is going to be for them to place braces between the joists, so I'm confident that'll do it, it's just about how hard I push forest river now I guess. I've actually been really happy with the overall quality of this particular RV thus far!

Braces should help for sure. I know Forest River has a brand or two under their massive umbrella, I may just be looking at too cheap of campers to have seen anything of significant quality yet.

I went into this purchase knowing it was an entry level 5th wheel. I paid 51k OTD on a trailer that was 65k everywhere else, so I got a good deal during covid. It's the cheapest 43 foot camper that's a mid bunk I think you can buy, but if you go into it knowing it's not made like a tank, it should be fine I would think. Me, my wife, and my two kids love it, it's huge.

I was surprised to find a 2x is really less than 2x4. It is all marketing.

5/8 inch plywood is not less than 1/2 and inch thick.

 

[Bob K4TAX]

The standard thicknesses for plywood are 1 ¼, 1 1/8, ¾, 5/8, ½, 3/8, ¼, and 1/8 inches. The corresponding actual thicknesses are 1 ¼, 1 1/8, 23/32, 19/32, 15/32, 11/32, 1/4, and ⅛, respectively.

So the short answer is yes, I was duped. It's not 5/8 inch thick plywood

 

[Bob K4TAX]

Is the 5/8" issue publicized in the documentation or something a salesperson said? If it is what the salesperson said, that is as reliable as a hole in the bottom of a coffee cup. Won't hold coffee or water.

Sorry if I offend any salesperson here in the group. Just having to lump it all into one pot. I'm sure there are some knowledgeable and reliable salespersons. Hooray for you. But then I regress...........

Let's look at this a different way!
You like the rig?
You know the floor gives.
You investigate for an over abundance of caution.
A little investigation shows the frame work is less than desirable, but you now know that the builder used 7 ply plywood for the floor. You are elated to find they didn't use the cheapest stuff on the market. They aimed to offer something light enough that you don't need a troop carrier to move, by simply installing less wood of a higher quality.

You rest assured, that it would take quite a flood to damage that higher quality plywood. And though you know it wasn't built the way you expected, you have something that can serve you for years with the materials they chose.

Put another way!
You were happy with it when you bought it! Why spoil the joy! Live and be happy!!!
