Nice Job,
I like the idea. It's nice to have options but in general I want to place the genset farther away form the RV. A 20# or 30# tank would allow a lot more flexibility as to where to position the genset vs. the hose.
I see the hose as more of a limit and liability vs. the freedom provided by an additional tank.
I guess there is no harm in having the option to connect to RV or use a tank.
I don't do NASCAR camping but I can see where having the genset close the RV would be beneficial at a race track. Otherwise I want the genset farther away than the hose allows.
Consider putting quick connects on the regulator you removed so that you could easily put the regulator back into the system and connect to a propane tank with out using any tools.
