Is it possible to use an outside propane grill hookup to supply the trailer propane system with propane from a 100 lbs tank?

I'll hazard a guess, but if I understand the configuration, you would be backfeeding the system downstream of the regulator. That may not be advisable. Prior threads of folks using a 100lb tank mention having the tank provider make the necessary hardware/regular hookups to do it.

Yeah, so I am currently thinking one would need an appropriate pigtail to connect to the regulator where the existing tanks are.

Jackfish, that sounds logical. My thoughts would be to connect the tank as a replacement to one of the standard tanks and that would allow your 2nd tank to become the spare tank. When the big one runs out, the regulator switches over and you have time to get the big one filled.
