I don’t know the specifics of the rack you were (are) trying to attach the awning to but wanted to throw this out to you just in case you haven’t come across it before.
I’ve looked at them for some possible mounting solutions to awnings I have considered.
Looking forward to your trip report as my wife and I will be making a trip to Telluride in September for the Blues and Brews fest and currently plan on traversing the Imogene Pass and other routes in the area.
For just about anyone else, it would be too hot then... Coming from Phoenix, it should provide a little bit,of relief.
Your time frame is leading up to a busy period for me in my “side hussle” but I’d be interested in a possible meetup. I might not be able to make it all the way down to Big...
