We bought a 55 qt rotomolded cooler last summer to support our camping ambitions. After using it a few times, we decided it was a little too big for our vehicles when we pack with a family of four and a dog. This cooler is rated bear resistant and should keep ice cold for 5-7 days. I used it on my 8 day trip to Canyonlands Needles district in September and it did a great job of keeping our items cold and ice frozen for the remote camping portion of the trip (4 nights, 5 days). The cooler has a drain port with a threaded cap and can accept a hose to drain water away from the cooler. We've moved on to a 12V fridge and battery solution and no longer see a need for this cooler.
This is the cooler I am selling. https://www.walmart.com/ip/Lifetime-...0949/490384164.
