I had a 7300 for about a year or so. I bought it in anticipation of doing the C&O Canal trip but then was not able to go.

Mostly I used it for groceries - had 2 sets sm/large panniers that I could use to go to the grocery store. It was a nice bike and if I didn't have 2 other bikes would have used it more. I finally sold it (for almost what I paid) because I found that I just was not riding it. I never really liked the flat bar position and since I only ride on paved surfaces, did not need the fatter tires and suspension.

I have a Trek Portland that I use for commuting and all my hauling needs. It has drop bars and with slightly wider tires (28) it can handle bumpy roads just fine. In fact, I still think it's my favorite bike. Of course this is a much more expensive bike If you want to go this route, note that the current models are being sold with Tiagra, but the older ones had full 105, which I think makes a huge difference. If you can find an older one (and cheaper) I'd recommend that over a new one.
