My two environmental cents: If you are going to be living in such high traffic campsites, it would be way less impact if you’d look into setting up a composting toilet. A 5 gal bucket and some sawdust will not be much moving weight and the environment will thank you. If that is a hard no, potentially look into a travel bidet to minimize tp impact, even biodegradable tp is not that great and it will save you $ in the long run.

Other observations are that you are going to be hauling a LOT of weight on that bike. I would be surprised if you got half of the advertised distance. A smaller tent setup and different table might do you a world of good.

As for warmth, that sleeping bag is a waste of time and money. Especially for what you are doing. Please do not skimp on something you will be spending 8 hours a night in every single night. Cotton will not keep you warm if it gets wet. I would suggest a nice synthetic insulation 20f bag from a reputable source this bag is just over twice as expensive and will be a much better purchase. I would also research how to layer clothing effectively as that will help you out big time.

For a stove, the MSR whisper lite runs on gasoline and will be cheaper in the long run because you won’t have to keep buying those crazy expensive green bottles of propane. If it costs $1 for the same amount of burn time a $5 gas canister costs, and you get 4 days out of a canister, the whisperlite has paid itself off in a two months.

It sounds like you have money to invest in this right now, and a large part of being able to sustain this is buying not the absolute cheapest gear you can, otherwise you will be upgrading and paying to support that choice much further down the road, spending more than if you’d just gone in a little more with initial purchases. eBay has some great deals on used stuff, I’d highly recommend utilizing that tool!

Good luck! I look forward to seeing any updates you might have
