I added a WDH to my Sierra Denali/StarCraft even though the tt didn't even bring down the rear of the TV 2 or 3 inches. The TT is apx 6750 and the Hitch is 730....and even though the Denali handled it with ease, I wanted just a little extra....that and the sway bar already attached.
On Monday, the day after the races here in NH, a TV/TT went sideways in the road on a beautiful day, no wind and dry. I am glad it happened after I secured for the day, but would have loved to hear the story. Will fill you all in when I talk to whoever was assigned. My wife told me it looked like a Ford 250 and a 30 footer......my guess....no WDH to begin and no swaybar?
