I have a Yeti 65 and got to say it is a awesome cooler. We got it because we leave our camper in storage at the campground that we go to and have to bring in all our food for a weekend trip. We usually get set up Friday night and the once the fridge get turned on it won't be cold enough for use until Saturday morning/afternoon. With the Yeti, during this 16-20 hour time period, none of the ice has even melted, our food is cold and never wet! I also like the fact that I can easily secure the cooler to the camper by using a cable lock and also secure the lid by a separate lock to keep the teenagers from helping themselves to my beer in the middle of the night once it is switched over for that use for the rest of the weekend.
As for bears...don't have to worry about those, but that lock that I use for the teenagers will keep the big furry ones out too! ;)
