Concerns About Going Full Time

You will want more propane capacity and lower cost. You could get 1 or more 100 pound propane tanks, find your parking space next to a pole or something that you can chain them to, then run a hose into the propane compartment of your camper. The big tanks are way cheaper per gallon to fill, and will eliminate the frequent fills. You could probably even arrange to have then filled right there at the marina by a delivery service. Just make sure you get vapor tanks, not liquid tanks. Liquid 100# LP tanks have an internal tube from the valve to the bottom of the tank so they draw the liquid off the bottom. They have external threads on the valve. Vapor tanks draw gas from the top of the tank as it evaporates off of the liquid. 100# vapor LP tanks have internal threads.

Or else you could get a propane supplier to lease you a large tank, 100 gallons or so, and keep it full for you.
