Thanks for putting your efforts into this. Sometimes, things are just not meant to be. Better to make a decision and pull the plug now than wait until later.
My wife and I will be in the area sometime in 2016 and early May or after Labor Day are the most likely times. If you're willing to put together some information and make it available via PM/email that would be helpful. We'd like to include some of the stops you and Ray had in mind.
If this trip or something similar comes together for 2017 we'll hope to join you then.

Got a cooped-up feeling, gotta get out of town, got those Airstream campin' blues...
