This is by no means a minimalist list of camping requirements, there is a trade-off between lightweight and comfort. My preference is for a slightly heavier and roomier 3-man dome tent so that I don’t have to contort myself getting into a hiking tent. Comfort is also the excuse behind the three legged camp stool and air mattress being included. My head may well keep telling me that I am still twenty something, but the body disagrees and vocally reminds me at times that I am actually in my mid-sixties.
My advice is to pack for a low level of comfort but be prepared to “donate” some of this extra weight along the way if it turns out that the bike is too heavy regardless of what you convinced yourself.
But, having scaled your list of gear down, sometimes the reverse is required.
A big factor for my Desert, Dust and Dingoes ride in 2016 is that I will be hundreds of kilometres from the nearest corner shop most of the time. The list above will by necessity, have to be stretched to provide food and water for 5-6 days while in-between restocking options.
