REI Croozer

I've been looking for a decent dog trailer for years. Even bought a Burley
D-lite to fashion it into one. I just happened to see this on REI website:
http://www.rei.com//ProductDisplay?p...8000&langId=-1

It's $250, which is definitely a good price. It's good up to 100lbs, but
the 29 x 20 x 24 dimensions seem to be a little too small for my Lab.
Anybody has any experience with this one? TIA.
