Most manufacturers recommend sway control bars above 5000lbs.
They recommend a fifth wheel over 12,000lbs

Kind of.. go look at your hitch (the receiver on your truck), there will be a sticker with two numbers, one with WD hitch and one w/o.
Also, just as an FYI You are mixing up terminology.
Weight distribution (WD) hitch, that is the one typically with the bars/chains (Equalizer is a brand name).
Sway control is something different, although most of the higher end WD hitches have them built in. Most people use the cheap (and IMHO useless) friction slide styles.
You SHOULD be using Sway control on all trailers above 5000#, whether it is one of the slip/friction bars or a proper sway control hitch. << This is where your above 5000# weight trailers applies. Note that you can use a Sway control device w/o a WD hitch.
WD should be used as required by your hitch receiver OR if you notice that your truck does not sit level or at the same relative angle as unhitched. WD transfers weight to the front of the TV, which in turn improves steering and braking.
Now this is where it gets more confusing, you have to keep under ALL your weights. As in, you need to make sure your are under your axle weights, as well as all GVWR, GCVWR, hitch, ball, shank, receiver, blah, blah blah. As an example, you may need to use a WD hitch to stay under your rear axle rating, even though your receiver says you don't need it. That is more common to SUV's, 1/4 & 1/2 tons.
Basically, WD makes your truck and trailer move as a single piece in the vertical axis or up/down (as much as possible), and forces your suspension to work properly (not porpoising). And sway control forces the trailer and truck to stay in line, side/side.
Sorry for the BLAB.. There's so much bad information out there regarding towing it's downright scary (I don't mean anyone in particular, just in general).
I really wish the Alberta LEO's would start enforcing this stuff.
