Add another Otter owner to the list. I also have the 14L X 7W Otter, and love it so far. I added a few D-rings for rigging, but other than that, it's perfect for me. I've done 1 overnight trip with it so far, and it held enough gear for me and my family. Granted, I went with a group, so we didn't have all the gear I'd need to do it alone, but I think I can still get enough of the other stuff (didn't take a firepan, stove or toilet) on it to make over night trips work just fine.
For day trips, which I did a lot more of this year, it was perfect. Stable enough to feel safe and comfortable when the kids are with us, yet small enough to get a good ride on class III stuff.
I think if you are looking for a 14 raft, you can't really go wrong with the Otter (either width probably).
