I have a free standing Avalon APG. Yesterday it shut down due to low/close to empty pellets. I could see the blade that cuts the pellets so I added a 40# bag. That bag basically filled the entire hopper..maybe could get in 10 more pounds. I thought the capacity was 80#'s??? And I thought only the insert had an adjustable hopper size?? So does your free standing unit hold 80#'s??
