John, are you attempting to connect the Roadtrip to a built-in propane quick connect connection?
If so, this won't work as is. The RV's qc (quick connect) is made for a grill without a built in regulator (sidekick grill, RVq, etc).....since your RV's gas line is already been regulated by the time it gets to the qc.
The roadtrip has it's own built in regulator, so in essence you are double regulating the propane when attempting to use it with the qc. You will get a very low flame because of this.
We have many threads on this, and what you must do to adapt this. You either must remove the roadtrips regulator (if possible) or absent that run a line/T off of your propane tanks BEFORE they are regulated.
