For the propane I bought 2 5 ft extension hoses from amazon.
CISNO 5 Foot Propane Tank Extension with Gauge Acme to Male QCC/POL Fittings
I took the propane tanks out of their cubby holes and place them on the ground along with 2 other 30 pound tanks. Hook these hoses to them and switch them over when they go empty.
I used to deal with a 100 pound tank but at 62 years old I'm not lifting them anymore.
