2014 Airstream Interstate external propane

Can an external propane source be hooked up to an 2014 interstate? There is a quick coupler to feed an external grill but I don't know if you can put a 20 lb tank on the coupler and feed the motorhome (gas flowing opposite way). Any help appreciated

I don't know about the AI specifically, but typically the high pressure side (prior to regulator) manifolds come in two types; 3 way feeds an external grille (and includes a one way valve) or 4 way which allows connection of an external cylinder (that port is an open connection and needs to be capped if not in use).

So I would take a look for the unused port on the manifold (typically at 90 degrees to the 'gas out' port).
