Reddit mentions of Coleman Beverage Cooler

• A thermos of hot chocolate/soup is magnificent.
  
  
• Bring a Snickers bar for after the dive too. The sugar and protein can get your blood/metabolism pumping and it's a good snack to hold you over until you get to your next hot meal
  
  
• Fill a ≈gallon sized, insulated jug with hot water and do your best to keep it warm (wrapping it in a towel or some neoprene material from a fabric store works great). Dunk your hands in there if they're too cold to move around (it's hard to warm up your hands and fingers). Otherwise, don't forget chemical hand warmers packs (but they stop working once they get wet)
  
  
• An extra towel and a complete extra change of clothes are a good backup
  
  
• Have a setup plan and stick to it to change in and out of gear. Minimize any time where you aren't wearing a hat/gloves/jacket/etc. Body heat is quickly lost and it takes forever to return when you're wet and your body temp is down
  
  
• Ditch your gear, and immediately get out of your wet scuba gear. Break down your scuba rig well after you're dry, warm, and stabilized

Also, I agree with the advice about an air mattress - get a cheap one with a battery operated pump and maybe a cheap patch kit to hold you over if it blows between Walmart stops. Replace it when it won't hold air, ditch it at the end of tour.

It seems like what this woman is trying to do is noble, but many of us have been achieving the same thing for years with one of these. It's a fraction of the price, is durable, has a convenient carrying handle, and is easy to clean.

I love making red beans and rice or chicken and rice when out backpacking and camping this way. Boil some water at breakfast. Pour it into the vessel with rice, meat, and seasonings. At lunch you will have quite the meal, with very little fuss.

I've had success with small water jugs. Keeps the temp just fine and then I finish it off on a cast iron pan.

Cheap and insulated.

Just make sure to rinse out whatever container you use, and don't use detergent or soap on it.
