The Equal-i-zer 4-pt WDH has integrated sway control. It is a great WDH with many satisfied owners.
Your truck should tow that TT pretty well at or slightly over any of its ratings. I recommend not relying on the RV dealer to properly adjust the WDH. Some are good, many are bad.
Start reading here. Learn how to adjust your own hitch as some changes to the truck will require adjustment anyway. A
CAT scale will help, but I have been satisfied with the fender height measurement using 2 tow vehicles with the same trailer.
