Here's a pic of the two way (electric/propane) freezer inside the trailer. It's @ 3 cubic feet in interior size, and will freeze @ 25 processed sockeye salmon, which is @ half my seasonal limit set netting from the beach (my limit is 45 salmon, including sockeye, pink, and chinook). It uses less than a single 5 gallon propane tank for the 3 weeks I'm there, including the time before I'm even catching fish, but have steaks, pork, and chicken in it for me and my visitors to eat. When the freezer gets full, I transfer the processed and wrapped meat to a large ice chest which I bring to a nearby town @ 25 miles away where there are businesses that rent space in big commercial freezers. I start all over again filling my own freezer until the season ends, then pick up my ice chest on my way home. This allows me to stay on site and not have to run around like everybody else looking for ice (@ $5 per bag) to keep my fish cold, and it allows me to process on site. When I get home, all I have to do is put the fish in my upright freezers at home. In late fall, when hunting season is over and I've winterized my home and vehicles, I thaw what I don't think we'll cook and smoke/can it. Canned fish will keep for 2-4 years. Old cans are great doggie treats, but we're really good about eating them up, or giving them to folks way before they're old.
