To put the math into a situation.
Go pickup a 4x8 sheet of plywood and stand into a 3mph wind.
Multiply 4x8 to the size of a slide side.
My little 24.1 slide is 78x78, 42sqft+ vs 32sqft for the plywood sheet.
The 3mph wind would push you down.

10,000 times the pressure of the bellows.

Bigger slide=exponential pressure yet same bellows due to same massive rv leaks.

Look at that chart and be astounded why a boat can be pushed by a 3mph wind. Lots of psi.

It doesn’t work that way.

Besides, I don’t know what numbers you’re reading, but a 4X8 sheet of plywood in a 3 MPH wind wouldn’t push me over. It’s so low a force compared to weight it would be hard to feel.

And 10,000 times more? Where are you getting the “bellows” pressure from? That’s not an easy pressure to calculate.

Actually, “IF” an RV could be sealed tight, the pressure fluctuation due to a typical-size slide opening or closing would be far greater than created by a 3 MPH wind.
