+1. As someone who does loaded tours, I have encountered LONG stretches with no where to refill from clean sources. Just had a couple back in June. Both were about 50 miles with 4,000'+ of climbing with passes close to 6,000' in altitude. One climb was all dirt/gravel, and it was quite warm. Two 25 oz. bottles and a 40 oz. CamelBak. For the second one I took an additional 1L soda bottle as an emergency backup. I did that same route 2 years ago in high heat and humidity and went through nearly all my water.
The "I only need this so you shouldn't need more" mentality is myopic and suggests a lack of varied experience.
