Yes. You should find everything you need at sites like http://caloreequipment.com/. The two types of quick connect are the low pressure 250 series of connectors and the high pressure 5LPN. The two are not compatible. The way to tell which you have is to look at the female end of the quick connect. If it has a small round tube in the center it is the low pressure 250; if it has a small bar in the center it is the 5LPN high pressure.
When you do this though you need to replace the regulator that normally comes on the grill where the small bottle attaches, with just a valve assembly. The propane connection coming off your RV is already regulated and having a second regulator in the circuit will not work.
