Sorry, Ranger Smith, but the LP line the OP referred to is NOT Liquid Propane, it is Low Pressure.
To the OP, it is true you do not need the regulator on the grill. However it must be noted that not all grills are usable with that low pressure gas line. If you have a grill that does NOT have separate regulator and control valve, it won't work without more modification than it is worth.
If your grill has a separate flame height valve, all you need is the male quick-connect and a hose. And maybe a couple reducing couplings. You should be able to get the parts from about any RV store. If the store can't fix you up, that will tell you something about the store.
Do be aware, however, that there are two quick connect fitting sizes in use. They look identical to the eye, but are just enough different as to be completely incompatible. I have no idea which one you have on your rig, but my local dealer describes them as "the old one" and "the new one." Whatever that means, for I haven't found any rhyme or reason to the age of trailer on which they are used.
You can get the male connectors for about $7 a piece. If it was me, I'd go buy BOTH, and at your leisure, return the one that didn't work. That's what I did.
