Hello. 2008 Thor Hurricane 34B.
Our daughter has been living in it since the end of June while awaiting getting her own place. Had to fill the propane tank recently and within a day or two it was completely empty.
Looked underneath I found a female threaded receptacle which obviously something fell out or was removed since the brass threads are “like new”.
What exactly is this? A low point drain? Could this why the tank drained so quickly?

Some propane setups come with a manifold where the LP can split off to furnace, hot water heater, stove, oven and external bbq. Should there be more outlets than needed the manifold may have a "plug" on an unneeded outlet. If that plug is loose or missing then you would lose LP from it. Maybe post a pic for folks to look at

could it have been a stub for a propane bbq and somebody stole?

That female threaded fitting is the hI PRESSURE fill nozzle. The Threads look new(clean) because this fitting usually has a yellow cap installed. You remove the cap to install the fill nozzle. Since NO yellow cap, then it has been lost. Obvious cause of no LP after fill is the filler did NOT fill the tank full. If it leaked out the usual 15 to 25 gallons of LP in a few days you would hear it and smell it. You need to get a cap to cover the fill nozzle. This link shows what it is. Doug

If it's at the bottom, it might be a liquid withdrawal port, sometimes used for LP generators.

Photo please
I will add the Fill port is kind of large... it is outside thread (The fill nozzle fits OVER it) I'm not sure why you'd call it female save the hole in the middle... There is a check valve behind it.
There is a three 'Fingered" knob valve beside it (The Visual Overfill Indicator Valve" if the fill tech did not fully tighten that will leak you will Smell Propane if that happens. (You may for a bit even if the valve is properly closed as some propane is vented during filling)
THe other fittings on the tank are smaller
IF you have a gauge on the tank the Fill port is, as I recall Larger. (The other ports smaller).
Home was where I park it. but alas the.

Thanks for the responses so far. This female threaded part I am referring to is on the underside of the propane tank itself and is recessed into the tank. Not a location that would be easily accessible for a temporary or permanent attachment of any sort of bbq or the likes.
I am unable to upload a picture for some reason.

Fill the tank then take a piece of masking or painters tape and place it over the port. Spray or even dribble soapy water around the tape and see if you get bubbles. The tape is to narrow the opening that the gas is escaping from to help it bubble.
But realistically you should be able to fill the tank, turn it on it's side, lean over and put your nose against the hole and take a sniff. If it's leaking you will know.

Realistically, it's a bit of a project to turn the tank on it's side - it's installed pretty sturdily under the Class A motorhome...
