I have a very similar setup, perhaps also owing to being a larger individual.
I don't think that water bottles, headlamps, trowels, and towels belong in the luxury category. Camp chair, definitely, especially if you already have a bearvault to sit on.
How do you carry your bear can on/in your pack?
I keep most of my cooking and personal care stuff in the bear can, and the shadowlight has a nice thick pad, so I put my sleep system in the trash bag on the bottom, try to center the can as much as possible while upright, tent on one side with ground cloth wrapped around the poles on the other and mostly just try to cram anything else around either side just to keep it stable.
I put my water bottle in luxury because my filter holds water, the headlamp because I have a phone with a light in my pocket, historically I've cleaned stuff off with my shirt then stream washed my shirt, and I have dug cat holes with sticks. All that stuff just makes the trip easier, but I could survive without them.
Those are all good points. I would still disagree with the nalgene because I consider having a spare water container a just-in-case necessity (I just roll up a spare one liter soft bottle into a side pocket).
I carry my gear quite similarly, with some of the differences being that I pack my tent sideways on top of my bag/quilt, and spread the footprint out on top of that. My bear can fit sideways in my pack, so that gets placed at the top of the stack and the rolltop lid closes nicely over the whole thing.
I'm totally with you on the camping chair. I consider it a nonnegotiable luxury. Jetboils are awesome. Could cut some weight by swapping out the bear vault for and Opsak Loksak. I haven't had any problems with critters being attracted since using that and it weighs nothing. I do put that inside a more durable sack and hang up in a tree. Another luxury item I like to take is a hand chainsaw. Very little weight and makes cutting down bigger sticks much easier and safer. Overall sounds like a great setup friend!
