A 30' TT will likely have too much hitch weight for your truck. So not only will it overload the hitch it will cause a nose high condition for the truck. Using a WDH doesn't "cover up" handling issues, it prevents them because it transfers the hitch weight forward on the truck. So all that weight is basically sitting in the back of the bed instead of hanging off the back of the bumper where it has far more leverage over the TV. You don't want to find out the hard way that your truck has sway, like coming down a mountain pass.
