Just for clarification, it's called a WDH (weight distributing hitch). Most vehicle owners manuals will state what trailer or tongue weight will require one.
Some WDHs have built in sway control while others need a add-on friction bar.
Generally speaking, unless you have a 3/4 ton, you should have a WDH to pull even a hybrid. Unless it's the smallest of hybrids and you have a 1/2 ton.
