13fido13 - You're the first one I've come across with the exact same wagon, they seem to be quite hard to come by.
The roof setup is as follows:
Yakima Railgrab - http://www.rackattack.com/product-pages/yakima-railgrab.asp
2x Yakima Highroller - http://www.rackattack.com/product-pages/yakima-highroller.asp
Yakima Fairing (Not sure the size, I think 32") - http://www.rackattack.com/product-pages/yakima-32-inch-fairing.asp
I've used the setup almost everyday for the last 2 weeks and it's super easy to get bike onto it and off of it.
I wish I was able to make this weekends meet but I was up in Hamilton. I'm not missing the next one, seems like it was a blast.
Do you have any full car shots of your wagon? I'd love to see what you have done to it.
Here are some more recent shots of the wagon:
