I only do local rides. No touring exp. yet. But I have ridden some aluminum framed bikes and compared them to my various steel bikes. I am in my 40's. When I ride aluminum framed bikes i feel like they have beaten me up, especially over longer distances. So when i read that ad for the bike you are looking at, I see an issue with the aluminum frame. I dont want to ride that frame. I have read that Cannondale touring bikes from the 90's that had aluminum frames were considered harsher riding than steel bikes.
The other thing i spotted in that add is the FSA crankset. I have been shopping for cranksets for my bikes. Reviews I have read about FSA cranksets generally are not so good. They are cheaper than Shimano generally, and often included in new bikes to keep costs down from an all Shimano component bike, from what i think i know.
So what i would do with those parts is take them all off and put them on a steel frame, and get a better crankset. I might pass on the deal, because if you arent going to use the frame or crankset it isnt such a great deal.
I wouldnt want to ride that frame on a tour. That is just me, and i havent ridden that exact frame. But i can tell you i did a 30 mile ride for example on a Fuji 1990's hybrid aluminum frame on a rented bike and i felt beat up. I have an aluminum framed folding bike and it feels like it beats me up in long distances too. I rode 50 miles on my Jamis steel framed touring bike yesterday and i feel fine.
I also test road a modern low-end Trek aluminum road bike (with carbon forks) not too long ago and i didnt like the ride either (comparing it for example with my 1982 Trek steel framed bike.)
You could get a new Surly LHT frame for about $400 and move all those parts over. It would be better.
