It's nice to be able to split up gear between bikes, one guy carries the tent, one guy carries the ground cloth, another guy carries the stove while the other brings a fryin pan, etc. I'll even extend that to, one guy can bring carry a 1/4 drive socket set, the other guy some open-box end combo wrenches, etc. Tools responsibility can be split up a little to. Oh, I ride a KLR, tools mandatory. Then you don't need em- it's a Karma thing ~
Never do anything you would be uncomfortable explaining to the paramedics...
