I don't see much type-in potential for tenting.info, since "tent" isn't really a verb. Your domain is short and easy to remember, though, so if you develop it and publicize it to people who go camping, you could have something.
There don't seem to be a lot of worthwhile one-word .info's available for reg'ing. I prefer a good two-word one to a fairly meaningless one-word. (In the past month, I've reg'd names like FluMedicines.info, VHSmovies.info, & Cheap-Tickets.info; the last one already brought $39.)
Good luck!
