I might be pretty proud of an rv that could generate a bellows affect.
There's no need to cause concern or plant suggestion in people about a bellows effect.
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.
