Reporting back - I bought it.  Measured carefully and decided that load capacity would be manageable.  Didn't have a chance to paddle it, so I negotiated an even lower price.  Worst case - next year after some trial runs, I might decide it was not the boat for me, but at the price I paid, I won't lose much.  And, who knows? Maybe it will work fine.  I appreciate those who shared their wisdom and opinions!  Maybe you'll see me in QPP next year!  Thanks all.
