Sorry,
Just saw this. FWC was awesome, but I feel like it was a little too heavy for the Nissan. By the time we were loaded up with all of our gear, we were about 1000 lb over GVWR. I was fine with that on the highway, but not offroad. We also like to take 3 kayaks with us. The roof can handle one, but three is too much for it, it is hard to tie down stuff on the roof too, because you can't stand on it.
The Habitat is definitely not a FWC but keeps us dry and comfortable. We can stand on the roof to tied down, and it is super easy going down trails. We kept the OME HD suspension and air bags and are happy with our change.
