Is 11" the correct pressure BBT? I know its around 9" for Nat. gas.
I had someone tell me once about oil or some other fluid that's in the bottom of the tank, that you should not tranport the tanks lying down as this "fluid" would get into the system. Is this actually oil, as in petroleum? Never quite understood what he was referring to but since have always kept my tanks vertical.

NOT 100% sure about propane, but I know Natural Gas, specifically compressed natural gas has petroleum oil/water in it, we have 2 huge compressors at work that boost the pressure to ~3500 PSI for our fleet, the oil/water has to be drained from the "separators" weekly. Both the propane and CNG vehicals have "separators" in the supply line to trap oil/water before it goes to the injectors. From what I have seen when changing the filters, its definatly oily water.
NOT an expert on this, but from what I have learned from co-workers in case I run into trouble with the fueling station when I am the leadman.

Not to detract from the tragedy that befell your friend but I think we're talking apples and oranges here. Attempting to fix the system in a proper manner is not the same as having a non-functional propaned detector and/or leak that leads to an explosion.

not to highjack here but while propane doesn't freeze...moisture in propane can freeze and cause a NO flow situation. Methanol is widely used as a dryer for propane.
If your tanks sit empty a lot...condensation can and will form when sudden temp changes occur with nature.
Ask your local propane supplier about this....and if you have a tank that does freeze..let them know...they most likely can get you fixed up.
Methanol added for moisture contamination is quite common for residential storage tanks

11" of water column is correct for "most" RV appliances. A homemade manometer can be made cheaply....HERE It does need to be verified -usually at multiple places on RV to ensure that the high usage appliances have enough flow and pressure at the device.
Propane can have a lot of oily residue -as stated by BBT, and needs the lines purged out but this is mainly seen in old units...

Or if you know an A/C guy you could pull a vacuum on the tanks, that will remove all the moisture and some of the oil residue.
