I own a new ATC Bobcat shell model. The propane tank is used only for my furnace as it's the only propane device in the camper. My question is since I sometimes use the furnace on a daily basis, and sometimes don't, should I disconnect the propane line to the tank every time I park the truck and camper, leave it connected for days when using it, or does it matter? The reason is that I'm thinking I may be pre-maturely wearing out the propane line connector (it's the manually threaded kind with a large green female adaptor) and possibly creating a situation where a leak may occur if I connect and un-connect it too often. Is this a concern? Thank you.
