the most recommeded WDHs, are the Equal-i-zer and the Reese Dual-Cam, since both have built-in sway control.
the E2(a budget Equal-i-zer with 2 way, instead of 4 way sway control) is a more affordable version.
i'm very happy with my 4 way Equal-i-zer. no drilling, no cheap friction bar and once mine was setup, never had to adjust it.
