We were in Alaska last April and saw a number of rigs hooked up to 100# bottles by the local propane dealer. Just a phone call was needed and they delivered the tank, hose and necessary fittings, and hooked it all up. Removal was just as easy. Although I use a setup similar to the "Extend-A-Stay", it is not the same. I created mine out of common brass parts available at a local hardware store because the "Extend-A-Stay" contains a flow limiter in their piece. When both my furnaces and a hot water heater would run together, my gas flow would shut down. By building my own setup I had no problems. Also, be advised some 20 and 30 pound cylinders also have internal flow limiters that will shut off gas under "all appliances running" conditions. The design of the OPD valve in some cases causes this to happen. The engineers at Manchester Tank directed me to tanks with the correct valves, and I've had no problems with 20# tanks I use in 8 years.
