I did the math. There is no measurable affect except in a laboratory situation with a slide. Then it is parts of ounces of pressure at many mph of slide movement.
A 3mph outside wind generates 10,000 times the pressure any bellows effect created by any of our slides could IF you could seal the rv dead tight when doing the bellows test.
It's tantamount to imploding a tissue box by pulling a tissue out too fast.

I don’t follow.
A 3 MPH wind creates almost no pressure at all. However, if you COULD seal an RV tight, a slide would create significant pressure (or vacuum). It’s easy enough to calculate — but it’s pointless since RVs are not that tight.
