Maybe it's because I'm not accessorized yet, but do we really need more storage space in less convenient places? My TSC box still has plenty room in it. But I haven't done that much riding yet. And certainly haven't been doing any overnight cold weather trips.
It definitely depends on where and how you ride. If you are riding with a group at an off road park, and don't get more than a few miles from your truck, you won't need a lot. We ride in AZ and UT, usually alone, often getting 50 miles or more from home or our truck. Sometimes in places with no cell service. Temperatures can easily change 30 degrees in a day. I try to be prepared for most situations. Not a complete list, but I carry: lots of water, many tools, battery jump pack, recovery gear, shovel, saw, extra clothes, rain gear, first aid kit, extra fuel, and much more. I will have a spare tire and wheel, so I will need a jack and lug wrench. Much of this stuff is rarely used, but I feel the need to have it. If I put the tools and recovery gear in less accessible locations, it leaves the main storage box for the cooler, jackets, rain gear, etc. This is all stuff that is always on the machine, whether I am planning a 10 mile ride or a 150 mile ride. YMMV.
