This^ is the only issue with not running one. That empty feeling that RVers apparently get in the pit of their stomach when they don't see the wdh security blanket in place....
No, you don't need a wdh. If the trailer tows like carp, you may want sway control (another security blanket that is likely not needed in many/most setups as well).
If it helps ease your mind, I've yet to use a wdh on any of the 100s of different trailers I've pulled over the last 30+ years. Including our current RV which is rolling down the road at 33' long, something over 10klbs (never weighed it) and hitched up, requires 30-40psi in the bags to level the truck back up. Tows yust fine.
However the correct answer is the 3/4" sag in your suspension means nothing. That's supposed to happen when you put a little weight in/on the back of the truck. Don't ask us. Take it for a drive and see if you're happy, not happy or freaked out about how it tows.
