A response from a post on this thread from long time ago that was made, 'what's the point?' There is a very useful organization with thousands of members called "SSCA, Seven Seas Cruising Association" and there is an Equipment List Survey compiled about every 3-5 years which the organization members contribute users experiences too. The list entails hundreds of areas and rates reliability, service, prices, etc which folks use in purchasing decisions. Like off-roaders, having a kit that fails offshore or off the road kilometers away from support or service can be trying or devastating. Although it is marine cruising (sailing/boating) specific, I hope something similar is generated by consumers/clubs for land touring. SSCA only assembles the information and distributes to the club members and is not liable..
Just a thought.
