You are welcome. But what I proffered, as did others, was straight talk, based in my case on more than 40 years in the saddle.

There is little doubt (though there is more, based on your first report) that you can accomplish this trip on a less-than-ideal machine, but questions remain, such as how you'll attach such accessories as fenders -- not "race blades", real fenders and wider tyres.

As you have chosen to haul a trailer, you won't have to deal with the fact that you can't easily attach a rack. That's a personal decision, but I'd never consider a trailer, which, IMO, completely destroys the handling of a bicycle. I am partial to a properly packed bike w/ front (lowrider) and rear panniers, which can actually improve handling/cornering.

If you are so inclined, you can peruse more words of encouragement on my page about touring bikes.

Good luck and tailwinds.
