First post here, so if this is in the wrong spot, you'll have to let me know. I am in the process of rebuilding an early 80's travel trailer. This unit has been gutted out and I want to make the interior custom. I have aquired a 3 way fridge from a motorhome and the copper propane line has been cut about 12" from the connection to the fridge itself. I would like to know , where does the lp gas line change from the rubber that comes out of the regulator at the front of the trailer to the copper that attaches to the fridge. Does it matter? Any help here would be appreciated....thanks...btw, the fridge is the only propane device I will be running in the trailer.
Often the regulator is bolted to the hold down bracket for the tanks so the rubber line from the regulator is fairly short - just long enough to let you move the bracket enough to remove and install the tanks. Typically the rubber hose transitions to iron pipe that runs under the rv and copper lines are T'd off that to go up to appliances.
If the rv is gutted you should be able to see the main gas line and where the regulator hose attached to it.
