Ultimately you have to do what works for you! HYOH You have so many options that are so light weight these days that it would not be a significant weight penalty to take one for even occasional hot meals/beverages and if you find you aren't using it, stick it in the bounce box in case you find out later on that you do want it. Give yourself some options. While no cook may work, you might get tired of it after several weeks and just want to mix things up. Don't put yourself in a rut before you even step on the trail.

Personally, I like the hot meals and because I dehydrate my own food and mix up my variety, it is lighter and tastes better to me than the mountain house types and I customize the spices to suit my tastes. It takes more planning of course but to me, that's part of the adventure! I like coffee in the mornings. Sometimes I like a hot tea at night. That's what works for me, but maybe not for you.

Whichever way you go, get out there and ENJOY the trail!
