This is why I abandon the touring forums for long stretches. There are simply to many opinions based on the limits of personal experience and or expectations. If there was a one size fits all bicycle touring package that people had been using for years with joy and success it would be so simple. But its not.
Personally I would love to try this out, and if I ever see myself doing a trip that justifies it would give it a go. There are some backpacking trails in the pacific northwest that are on my bucket list, and this would be great, as solar would not work that well there.
