We had been trying for several months to fill our propane tank and hadn't had any success, and now we had several freezes and our tank was seriously low. Mike checked the actual tank gauge and it said it was less than a quarter tank, while the gauge on the inside wall said it was one third full. So we made another call to Tractor Supply---because it was a Sunday and no one else would be open and to our surprise--they said they had propane and someone certified to fill us! Happy day! We tell the backstory of our saga to fill our tank which included our 2 last trips of 2023. So we're talking months of trying. Another 'fun' maintenance chore none of us loves doing... but have to!
