Champion Dual Fuel Inverter Q.C. to RV On Board Propane
I believe this assembly diagram and parts list has everything anyone will need that desires to run their Champion Duel Fuel Inverter by using their RV or trailer's onboard quick connect (aka the BBQ propane port).
The 4 fittings required should cost about $25 total. The mod retains the ability to run off a portable propane tank so both onboard and portable can work. When running from OnBoard, the RV's onboard regulators control propane flow. When running from a tank, the supplied inverter's regulator controls flow.
This mod does not change or alter the way running the unit off of gasoline works, that stays the same.
Lastly, if you want to operate on propane further away from the RV you can simply buy a Propane Extension hose (10ft, 12ft or 25ft) and run the extension hose from the RV onboard port to the Inverter's safety valve/fuel flow diaphragm.

My initial concern was that the RV Quick Connect system flows thru a 1/4 inch Quick Connect adapter. The Champion fuel feed passes thru a reducer just as it enters the Safety Valve (1/4" to 1/8"). F.R.Forum member "clutchD" and others have been reporting good success with the Champion Dual Fuel Inverters for quite some time so this stuff is probably moot. But just for grins, I continued my research working to ensure that the trailer's On Board Propane port would provide sufficient flow. I contacted Champion, Forest River, a Propane Equipment Supplier and a few others I've forgotten now.
The only thing left to do if one wants to be even more accurate would be to buy/borrow a Propane Pressure test gauge. Those gauges cost about $100 and come with a male quick connect that would plug right into the QC port. In the mean time, this may be helpful to go along with the diagram:
Champion Inverter Gas Supply required: “You need 1/2 PSI with a flow rate of at least 76,000 BTU/hour”
From Propane Gas Expert: “Most Propane equipment runs at 1/2 PSI and equals approximately 14 WC with maximum flow of 200 BTU/hour”
Typical RV Propane QC Port Delivers: .39 psi equals approximately 10” to 11” Water Column and provides 160,000 BTU/hour
F.R. Suburban RV furnace Install Guide: “Gas supply pressure for purposes of input adjustment: Minimum – 11” WC / Maximum 13” WC”
