My impression is that the relative lack of oversight is partly because this issue has fallen though the cracks in the U.S.
For instance, I was told by an authorized rep that the propane flex hoses that were used on my Class B (and presumably many others) are recommended for change-out every 5 years. Even if the tank is sound, the hose manufacturer will state that they don't believe its hoses are still sound at that point (more details here
If the hoses are, by the manufacturer's own definition, not sound, then neither is the system itself, really. But to my knowledge, there is no corresponding regulatory requirement to change them on a 5 year interval or any other interval. Nor is there anything mentioned about this in my rig's owner's manual.
Propane issues just haven't been dealt with very thoroughly, in other words. If this kind of thing were common knowledge and we had a 5-year inspection requirement, then at a minimum, hoses would get condemned every 5 years during such an inspection unless they had been replaced.
