Both Lance and Northwood make great trailers -- but nothing smaller than 17 feet. That sounds small, but for two people, you can really get by with a lot less. (We camp for weeks at a time in an X-139. The "139" is inches, as in "not quite a 12 foot box.")
Having a really short trailer means that we can turn around in a wide spot on a forest road, we can fit easily between trees when boondocking, and we have very few cubic feet inside that we have to heat when snow camping.
If Northwood made a 12 or 13 footer, I would be very, very interested. Carson Trailer, in Gardena, Calif., makes a nice unit called the Kalispell, but it is really cramped inside -- I am 6'3", and the bed was just too small for me. I think it was 54 inches wide. My wife refused to sleep on the floor. ;)
