I love Yeti coolers, but with their price and the size you would need to have ample interior space, they're heavy as s**t when packed. Kinda feels like you're a pallbearer at a funeral lugging the thing around.
FYI, I decided a few years ago to try a hack: I hot glued Reflextix to the interior of my Coleman 5-Day cooler and seamed sealed with the aluminum tape. I call it my "Ghetto Yeti".
Took a little bit of time, but it adds significantly more insulation. It'll now lasts 4 days/3 nights without and issue in hot weather. It never lasted 5 day. Funny how that goes.
