Does spending big bucks on an expensive WDH really make that big a difference?
I just have the stock one the RV Dealer put in the package, with friction sway bar. I find it easy to use, and it works just fine. I only have towed a little over a thousand miles or so. 90% on two lane twisty hilly roads and never have I felt a loss of control moment.
Me thinks it is akin to buying the best golf clubs or high end bike, makes you feel good, but not much else. Kind of like me buying Honda generators. I know that Champions would have worked just fine for my purpose, but the Hondas felt better.
