I rode the 60cm Long Haul and it felt awesome. I loved riding it and thought from a fit perspective that it was great. My concern is that it feels like a giant bike (big wheelbase, very upright) and once loaded up with 40+lbs of gear it will be tough to handle.
Just the opposite. Many people say it rides just as well if not better when loaded since it's designed to carry loads. I rode mine fully loaded for touring and "bare" for commuting. I don't think it handles any worse when loaded.
I am 6' 2" with a relatively short inseam (about 33") for my height and ride a 60cm LHT. I could have probably gone with a 58cm due to my relatively short legs, but I liked the way the 60cm fit "up top." My first touring bike was a Cannondale. Back then they came in only a few sizes. S, M, L and possibly an XL. I tried one size and and it felt a little cramped so I went with the next size up. From a standover perspective, most people would say it was too large, but I like the way both felt. My point is that maybe I am biased towards larger frames. Bus as others have said, if it feels good to you, go with it.
The LHT comes with a prettly long steering tube and a lot of spacers. You can always rearrange the spacers to affect the "uprightness" of your position. Some people (myself included) prefer a more upright position for long days in the saddle. I highly recommend not cutting the steering tube until you find out what works best for you after a good aount of time in the saddle. Also note that the difference in wheelbase between the 60cm and the 58cm is only .6". Finally, the stock bar on the 60cm is nealry 1" wider than that of the 58cm. Could make a difference if you have broad shoulders like I do. My road bike has 440mm bars like the 58cm LHT. The 60cm has 460mm bars. I can definitely tell the difference.
Good luck with your purchase.
