I agree with others – Philmont is a lot different than a true wilderness experience – its the activities, staffed camps, music, basecamp & traditions that make it special. Many of the treks are not that hard – though the altitude can affect some. We climbed Mt. Baldy which added some challenge.
If you train well for fitness, crew spirit and gear evaluation/familiarity its not such a big deal. We trained hiking mountains (800'-1500') prety much weekly for 6 months and did 3 campouts – an overnight a 2 day and a 4 day. Nobody attended everything but overall it was a good balance. We worked mostly on bringing up the guys who needed the most help – everyone was fit for the trip and we had good team spirit before we even started.
We used 3 jetboil PCS's for a crew of 12 – we used them 2 ways – individually boiling water in the jetboil pots and combining and also with the GCS potstands to heat water in one of the big Philmont pots. It worked really well – however our ranger said he'd never seen it before! Of course the jetboils were fast & great for tea & coffee too. The higher elevation makes them work better – it wasn't ever cold enough to be a problem.
We contemplated a lightwight dining fly but didn't get one – next time I'd do this too – its probably twice as heavy/bulky as it needs to be.
We used one Philmont rope for bear bagging but it was also very bulky – may try different next time. We did also use paracord and a biner/pulley combination just for the Oops bag which was actually mostly individually ditty bags – much more convenient and easier for one to operate.
We did bring mostly ultralight tents – 1 pair had a Philmont tent & the weight was about 2x and bulk maybe heading towards to 2x.
After talking to several crews who had been before I ended up taking 3 different seats… (of sorts). A trail stool <1Lb 7oz, a Thermarest lite seat (3.5oz) which I also use as a sleeping pillow/lumbar support/footrest and a thermarest trekker chair 10.5oz which I use with my thermarest prolite-4 sleeping pad. While it seems like overkill – I always had a taker for any empty chair and was always comfortable for <2.5lbs. No regrets on that one!
In our gear checkout our ranger spent over 50 minutes checking our gear – and asked lots of questions – but ultimately did not object to anything.
My total weight with water, group gear and 4 days food was about 40lbs – quite comfortable for me.
