For that hose explosion I would suspect a regulator issue becuase thermally expanding gas under ounces of pressure shouldn’t be enough pressure to split the hose. I would suspect that the hose pressurized up to the boiling pressure and the propane was liquid in the hose. Then thermal expansion from liquid blew the line. That would only happen though with a malfunctioning regulator.

It was a Canadian tire special that allowed me to use a full propane tank and not those little camping bottles so you are probably right.
