After reading so much about the possible problems with electronics I started to arrive to the conclusion that the problem is not the electronics but the luck of knowledge or information at reasonable cost that have the independent mechanics to perform the repairs or the owner/explorer
Are the software and diagnostic equipment ready available for independent mechanics at a reasonable cost and not at 5000 plus?

Sooner or later conservative people like me will have to bite the bullet and get one vehicle (regardless of the type) which is going to be equip with electronics.
Even the mighty Unimog has electronics for a few years now (admittedly the after sales service for the Unimog is one of the best in the world)
I am looking forward for your inputs and ideas in how you will plan and equip a vehicle with electronics for a remote expedition.
