I'll say it again - the only benefit to touring with tubeless is puncture resistance, which is really only a benefit if you wanna use light(ish) tires.
I have several thousand miles of riding (in Oregon and California, granted it's not Arizona or Australia) with 0 punctures.....with proper HD 'touring' tires like the Schwalbes. I have been on the tubeless bandwagon for several years with the other bikes but don't see myself going to tubeless on the touring rig. It's not field serviceable (in most cases) and not worth the hassle.
