Stoves are not needed for most touring. Yes way to many food threads. I wish we had more threads on finding water in the desert . I always hate myself when there is a gas station I didn't know about.

I carry a 1.5 liter and 1 liter in the frame. .5 gallon on top of the rear rack. 32oz Gatorade on fork. This is normal operation.

In extended periods one gallon and 2X 1.5 liters can go in my panniers (or strap them on). I use two rear panniers which are half empty.

Camel backs are too easy to drink from. I want something that will make me pause. Hiking is a different story.

You route should follow normal operations. Considering you are never more than sixty miles from services. Finding the optimal service between stops, may be the harder choice and I always fail at this part. Which is why I am so interested in your water stops Tucson to Bisbee.

The Coronado Trail has 90 miles of no services. Unless you consider the overpriced lodge at 70 miles and 10,549 of climbing with limited hours a service.
I ate two small meals and had 6-7 days of food with me. I also carried 3 gallons of water and asked a fellow car camper for .5 gallons more. I use my Gatorade bottle to steep food. Not shown in picture.
