why do RVs seem to leak so often compared to normal cars?

Question

Compared to houses, RVs are put under lot of stress when driving, but so are normal cars, so why are RVs specifically prone to water damage from rain or snow at considerably shorter distances than normal cars?

I once heard an RV rep say, “we don’t build them running!”
I know this isn’t an explanation, but a funny saying.
There are so many components and seams in an RV compared to a normal car, and the vibrations of the road exploit those, leading to more leaks over time.
