Old thread, but a good subject.
I have two upright freezers. The shelves, and door shelves are nice and much nicer than digging through a chest freezer.
I also have a chest freezer that we've used for transporting game. It's worked very well. Can either use ice, plug it in at hotel/campground or run a generator.
usually weight is centered obviously. That was just a temporary tie down to get a few miles to the road so I could butcher while others went to hunt.
