winters almost here-time to start cooking in my truck.Anybody have any good(or bad) experiences with the following:1)the slow cooker crock pot, 2)the lunch box stove, 3) Burtons oven with the 2 metal pans. Or any other cooking items that worked well. Also-who makes the best 12v 4-5 cup drip coffee maker-(and how long does it actually take to brew a pot). Thanks for all your info
