Hi all About a month ago, I started a thread with a question about propane that turned into a long discussion about what constitutes a tank vs a cylinder and lots of legal stuff. Anyway, ultimately, I took my class C down to the local RV dealer and he filled the propane tank with no questions asked. We are about to leave on our first ever RV weekend. I plan to leave in about 7 hours when my kids get out of school. I was just out going over things in the RV and realized that the propane was shut off ( I assume that was done when they filled it). I do not know how to turn it back on. This has to be the ultimate newbie question.... but I really don't know how to do it. The RV owner's manual says nothing except to use the main valve. It doesn't even tell me where to find the valve. When I open the hatch in the back where the tank lives, there is only one valve in there. When I turned that valve, propane started to "spray" out from the are around the handle. I immediately retightened that valve to stop the propane from spraying out. Is there likely another valve someplace? Help, please!
