Call George Randall Maintenance - he has the Kitty Bell on the lake. He services several homes and arranges for the propane tanks to be filled on shore and delivered back to your home. I don't know if he even does any rotation system where he switches an empty tank for a full one ? You can reach him at 603-253-7042 .
If you need any construction, repairs or maintenance work done, I suggest you call Lake Winni Island Property Management @ 603-253-7091 . Enjoy the island life!
