The bleed valve purges air and allows propane in the tank. You cannot "top off" your propane tank if the bleed valve is plugged. While filling the tank a couple things could happen. The first is the tank will not allow the dispenser to allow any more fluid in the tank as its preasure matches that of the dispensing unit. The other thing that can happen is you could have something rupture due to this higher amount of preasure. I would take this to a RV shop and get it looked as they have the knowledge to fix thisl.
If the handle on the tank is triangular, you have a OPD valve on your tank. To my knowlegde only the small propane tanks like the ones used on gas grills have the OPD valve. The federal gvmnt required OPD valves on the smaller propane tanks, larger tanks were exempt.
OPD tanks have been used on some motorhomes at least as far back as 2001. Our 2001 Winnebago Adventurer had one and so does our 2013.
I just wish they would coordinate the gauge readings with the ammount of propane the OPD will allow in the tank. The OPD only allows the tank to be filled to 80% of it's capacity. The gauge then only reads 80% full even though you can't put any more in the tank. I would think if the tank is at the maximum capacity the device will allow the gauge should read full.
