I can't imagine carrying a dutch oven. I strive to keep weight carried low and an item that weighs multiple pounds better be a necessity. I really like to keep the weight carried down to about 30 pounds including panniers, but not food or water. If you start taking stuff like a 6 pound dutch oven you will be up to 60-80 pounds pretty quick. Personally I would find that unacceptable.

I always advise new tourists to go light. You are way more likely to be miserable because you carried too much than because you carried too little. Witness the number of folks who wind up mailing stuff home sometimes multiple times. We mailed things home several times during the Trans America and even on subsequent trips where we carried much less to start with we have mailed things home to lighten the load.

If you later find that you like to carry more stuff do it after you have some experience with what it means to carry more.

Also, on any of the tours that I have done. Places where a fire was allowed were definitely the exception rather than the rule. Depending on where you tour this may or may not be the case.

I am pretty happy with a nice one pot meal. When there is more than one of us and we feel like going all out we accompany it with bread of some sort, a salad, and some wine. Typically our appetites are fired up enough when on tour that it doesn't even need to be all that exceptional to taste really good.
