I did some forum searching and it seems like most people had somewhat negative things to say about the original nashbar trailer, and better things about the new model. Some of the posts were a couple years old, so I'm wondering if the "new" model is the cargo trailer 2 or if nashbar re-made/re-worked the cargo trailer that's currently $79.99 since those older posts?

Looks like the 2 model uses large tubing and a different tire or fender. I have the original model and read many of the posts about it a couple of years ago. Many of the people that wrote about it were of the (yeah I put to much weight in it but it shouldn't have failed variety), never overloaded mine and never had any problems. it seems that the 2 model has a higher weight capacity 50 lbs as compared to 35 lbs. If full price 199 was the only option I believe paying 100 more for a BOB would be a better deal. It kind of depends what you are going to use it for and how often.
