Last month I did a four day ride on my Burley Hepcat. I will say that this was strictly a beginners level tour with little gear, overnights in hotels, and the forgiving terrain of Central IL. That said, I enjoyed the tour immensely and feel like my bike was the best tool for the job. I haven't used my recumbent for more loaded touring...yet. There are large panniers and midship racks available for the recumbent to put your gear where you need it. To find more folks that have done it, you might also want to poke around
Bentrider Online and ask some questions.
