This is all our gear for a 3 month tour, including camping/cooking equipment.

Those duffel bags look very fragile to me. How has this system worked out for you as far as the duffel bags go?
I used the same system as you on Amtrak, but my luggage on Amtrak never gets beat up that much so I trusted my lightweight duffels with them. But I have been too nervous to try that on airlines.
In post number 2 of this thread (above) the second photo shows an olive green canvas bag I used for the same purpose as your duffels, but my bag was much heavier and took up enough volume that I did not want to carry it on my trip.
