When I was full-timing I had a 60lb tank on a two wheel dolly, got the tank at Lowes. I plumbed a "T" in ahead of the regulator with a valve. Went to Camping World and got a 10' hose to connect tank to "T". When I needed propane I just wheeled the tank over to the filling station, filled, and hooked back up. Worked great, did 4 winters that way.
