Thank you to everyone for your responses. We have the 2.5L pots for our stoves and we take two of them so it is very easy to heat up water AND lots of it. AND, if we need another pot of water to heat up, it takes no time at all with the efficiency design of the reactor stove. I find you have to be careful with the amounts of water for a meal. We had a measuring cup (the one that comes in the useless mess kits..probably the only thing of value in the mess kit :) ) and would measure out the water. It seems like some meals the amount of water recommended was perfect. Others were like soup. Welcome to rehydration.
The pots are big enough to allow the santizing of the ziploc bowls, which is very important since the last thing I wanted on the trip was anyone getting sick.  We are NOT using turkey bags, so we are not part of the problem turkey bags cause by generating lots of waste. You need a bowl on the trip to eat out of so our ziploc bowls fulfill that need. The scouts kept the bowls to themselves but everyone had the exact same bowl. We were able to split the meals into the bowls with no problems. In 2013 and now, we practiced using the Philmont surplus meals and did not find any problems. Even with the “thanksgiving” meal as we called it (the one that has the Stovetop stuffing).
For the record, I am NOT a MSR salesman. I am an engineer by degree and 30 years experience and find the design of the Reactor stove great at trying to maximize heat transfer into the water. Nothing against JetBoil, but my preference is for the MSR design.
Our Ranger in 2013 was intrigued by our method and thought it was a good idea. He was working at Philmont before heading to the Air Force Academy.
In 2013, we purchased another canister of fuel at the commissary, mainily out of fear of running out. We had three 8 oz cans on the trip from what I can remember. Hard to believe six years have past since I was last there.
We sent the stoves ahead of us since we flew out to Philmont in 2013. We purchased our canisters at ToTT before we headed out on the trail. This year, we will have our own transportation so I can stop into a camping store in Colorado Springs and pick up our fuel there.
Again, thank you to everyone that responded back to my posting.
