Fastway E2 WDH with Sway Control

I know that several folks have this E2 WDH from Fastway.  Did you choose the trunnion style or round bar style and why?  Also, I'm assuming you went with the 600/6000 version.  If I wanted to swap this between my R-Pod and Jayco, would it be a problem if I got the 800/8000 version and still used that for hte R-Pod?

Square type, don't remember why I went with that version, its probable I caught a sale, too.  I received confirmation from the manufacturer that using a higher-rated model is fine to use with a lighter trailer so I believe the 8000 pound model would be ok for you.  I have the 6000 pound model.

I went with  trunnion . I don't think it makes a performance difference, but that is just here-say since I don't know for first hand observation.  The reason I went with it was the  trunnion  bar system does not hang as low and with my driveway the higher everything is the better. Someone on one of the other forums suggested that if you chose to strong a spring bar size it could stress the trailer. their reasoning was that if the bars were to strong the trailer frame becomes the weak link.
