I have found the most used tools on the road in all my Mogs are:
A good roadside recovery service
Good cell phone and service
Credit Card
Sense of humour
On Morgans Over America I carried many spares and tools of all sorts which were an insurance policy, only used the basic tools and duct tape for minor repairs. In the M3W both times I have broken down required the cell phone and roadside service, all the tools and spares wouldn't have helped.
