LPG Dual Stage Regulater Problems

BBB,we have 3yr old motor home & just replaced our's about a month ago.It is ok at the moment, did not get one from camec but some other mob that doe's sell c/van product's it is U.S.A made don't know how long it will last.3 is a bit much though.Bob.:)-<

Marshall gas is wrtten on it all i could see, as the gas bottle is in the way & i did not want to pull it out now. I think it was made in good ol' Texas.:)-<

This has been discussed on some of the caravan forums and some people are pointing the blame at the flexible stainless hoses from the bottle to the regulator. It appears that in some instances the gas has been having an effect on the internal rubber of the hose (questionable imported hoses) and this reaction has been causing a lot of the blockages. Some have replaced the stainless hoses with either a gas hose available from all car LPG fitters or a copper line. I would be more inclined to use a dedicated LPG flexible hose rather than risk a copper line fracturing with vibration.
Regards Andrew.
ps: installing the regulator above the bottle/s is also a good idea.
