^^The ice chest makers need to start making a self-propelled cooler.
Yes, but the old Coleman or Igloo may be all that you need. Add a bulb seal or gasket around the underside of the Coleman lid and a bungee cord across the top to keep the lid snug and that improves performance considerably. Just about any rotomolded cooler will be better than the Coleman by a decent margin, so choose your cooler based on price and physical configuration. Some are short/fat, some tall/skinny, some with handles that stick out too far to fit your ideal location, some with gear bags attached, some with standard interior baskets, some with optional baskets, etc.. Get what you want, because you will have it for a long time.Are they that much better than a budget-friendly Coleman 5 Day cooler?
TripLeader, did you ever find a new cooler?
I remember reading a tip somewhere quite awhile ago that the author suggested soaking a towel in water that covered the lid of whatever cooler you have and storing that in the shade to slow the melting ice. Just a thought especially if you're camping on a beach or desert where trees may be hard to come by for shade.
I have a yeti roadie for a beer cooler. Overkill for a beer cooler. But I got tired of replacing ice twice a day in the cheapo Playmate cooler I was using. The thing is built like a tank. You can use dry ice in it. While that's not a feature a lot of people might use, it speaks to the quality. I'm sure the cooler is going to outlast me.
Of course, there's this from the dark side: http://www.equipt1.com/i/fridges/indel-b
I have a 51L model mounted to a DIY slide-out and it's been very nice. The price has gone up to $600, but smaller options cost less; the only difference is the interior volume. Same compressor system as ARB and National Luna use, but at a much lower price point. My plan is to add solar charging to my roof rack, so I can leave the fridge on while away backpacking. It's not for everyone, but if you're tired of buying ice, it's worth a look.
