Iirc the 3 meter limit to the bayonet hose is a legal requirement for natural gas appliance not for gas flow. Think about it the gas has already traveled along 4 or 5 metres of small diametre pipe in the van.
Last year rather than picking up the baby Q at Rays with 25% off I got the gas attachment for hilly billy camp oven, but now regret not grabbing a Q as well.
What I have found is where they put the gas bayonets on the expandas 3metres doesn't necessarily get the BBQ or appliance where I want to cook and the bayonet fittings are very firm to fit on and off (which is good) and I like to disconnect gas after each use. So when home I am going to use my 3m bayonet hose fit a gas cock to the end and then a POL female fitting after that. That way I don't need a new bayonet hose for every or any gas appliance and i gain an extra 1.5m to get it right away from the awning and bed end, least that's the theory. I am pretty sure a reg on reg won't be a problem but I will check with a mate who used to design gas appliances for email..
Sorry for the OT
