jac,
I'm not familiar with this specific vessel but my instincts tell me it would never work for the way I travel... especially for a party of 2. So, I'd have to echo your concerns about load capacity. Admittedly, I'm a notorious "over-packer" and my motto: "If you don't bring it, you ain't got it" often gets me into trouble.
On the other hand, it MIGHT work well for you IF: 1) you intended to use it as a solo boat, OR 2) you are a single-portage packing sort of guy.
Me? I have plenty of challenges fitting what I need as a solo paddler into my Wenonah Prism... which is a full 1.5 feet LONGER than the one you're looking at. Of course, I'm packing camp chairs, extra tarps, plenty of fishing gear, etc. & so on AND I'm usually out for at least 14 days at a time.
Savage River has a fine reputation for making very seaworthy boats. Doing a little research on-line, about the only negative comment I discovered was over on BWCA.com. The fellow who posted really liked his Savage River, for the most part. About his only beef was that it "wasn't the fastest boat on the water"... which he went on to say that he didn't care about that, anyway.
If you are a "minimalist" OR a solo paddler, it would be my guess that it is likely a good deal for you. If you have some questions, it might be a good idea to request a "trial run." Take the boat out on a local lake & pack it like you would for your typical Northwoods week-long adventure. That should address whatever concerns you might have.
That's my 2 cents worth, anyhow. Good luck with your decision!
