I've been super glad I bought an "oversized cooler" years ago. If you ever decide to shoot elk or moose sized game, multiple animals, or meat plus cape it's always good to have more than enough room. I almost always save capes and sometimes life-sized skins.
Sometimes I'm in a hurry to get antelope on ice during the early season dates when it can be super hot so I don't bone them out. It's nice to get them in a cooler and not have to worry about room! I guess I'm picky and don't like my meat or capes wet. I make sure the ice is on the bottom with a layer of trash bags between the meat/capes and ice......and drain water as often as needed. Wet meat or capes is asking for problems on extended trips!
You may want to look at some of the youtube videos that compare different coolers melting ice vs time. Just because a cooler costs a small fortune doesn't necessarily mean it is better!
