How do I adapt my LP gas system so that I can hook up an external tank.

[SCPO_Al]

I have a 2020 Forest River Forester that has an internal LP tank.  I want to add an adapter so that I can also use an external tank for when I am onsite for long periods of time and not have to pack up and move just to refill my propane.  I do have a quick disconnect at the rear of the RV that I assume can be used to hook up a grill.  Is it possible to hook up an external tank there?  Will the gas flow both ways?

you could hook there, but you would need a regulator for the external tank you use and you would have to find out what the flow rating for the quick conecy is and if it is high enought to meet your usage demands, as in furnace and stove at the same time.

why do I need to loo it up..  I have no use for them.  I was ansering the question of weather he could hook up to the quick conect, which the answer is yes if you reduce it..
