most owners manuals have a towing section, which usually has a number that requires using a WDH.
as was said, the hitch receiver should have a label or stamp that gives a minimum number needed for a WDH.
you're pulling a single axle TT with a short wheelbase vehicle, HECK yea you should use a WDH.
not sure what "conflicting opinions" you're talking about.
i love my Equal-i-zer and there's no drilling needed.
