Nissan's Thermos Posted by: pikabike on Nov-25-12 11:52 PM (EST)
I have one that I used for desert winter car-camping. With boiling water stored before bedtime, about 12 hrs later the liquid was still hot. I helped it a little by putting the bottle on a foam or cardboard flat instead of directly on the truck bed. You can probably help it even more by wrapping in a blanket or foam.
