Do you guys think this is for liability reasons, or is there a serious vibration concern? Should I rip out the hoses and run copper or this marine hose mentioned earlier in this thread? I like the idea of being able to remove an appliance and then detach the propane line (i.e. it is hard to access my stove from the back without moving it. Luckily I don't have to move anywhere for a while so I can leave them in for now, but I need to figure out what to do safely for when I do start moving again.
For most connections from black pipe, copper is best IF SUPPORTED properly, and grommeted where it goes through floors/walls/bulkheads. There ARE flex hoses you can use.....
John, I advise against using NON-RV gas hoses. LOW-pressure hoses are available from RV dealers as replacements: use 'em! They are abrasion-resistant, and specifically designed for RV use. And not expensive, similar in price to home-oriented stuff...and a LOT safer.
Similarly, use the correct HIGH-pressure hoses between the propane tanks and the regulator.
This avoids the problems of having to frequently check hoses, fittings and connections using stuff that was not meant for RVs....AND THEN REPLACING IT ANYWAY.
I understand repairing RV and trailer pipes and hoses!......odds are, they were not installed and/or supported correctly in the first place, causing the problems. Take your time and THINK it over when doing the work. Working tired is dangerous, it gets you into thinking 'heck, that's good enough' when it's NOT.
Remember folks, a lot of thought has gone into propane use and RV design (and evolution due to tragedies!!!!!!!!), and following the best of RV practice is the way to go. DON'T RE-INVENT THE WHEEL! Being cheap is OK, PROVIDING you re-use materials PROPERLY and have INSPECTED the stuff you're re-using.
