That's exactly how life testing is done on many items, lesser pressures over long periods of esposure.
It is entirely plausible that 40# during travel will do more damage than the occasional heavier load under static condition.
It would take ~6Gs for that 40lb bottle to subject the ladder to the same stress as me climbing it. While it's possible, I question how often 6+Gs would be transferred through the suspension to the camper.
Actually that's not how items are stress tested. The item in question (ladder in this case) is subjected to a lesser stress but over a very long period of time (Known as HALT or HASS testing) to mimick long term exposure to what ever the stress thought to be.
So 40# bouncing over X thousands of miles can do more damage than one person that weighs 400# using the ladder only few times.
