Be aware that the statement above about the Equal-i-zer hitch having fewer parts than the others is not true. The Equal-i-zer, while an excellent hitch, has small clips, pins, and keepers that must be removed and replaced each time it is used and have a tendency to get lost. That is why they sell a spare small parts kit for it and recommend that it be purchased.
Here are some of the popular hitches being used today.
Of the regular hitches that use chains to draw up the bars, there is very little difference in the different brands. One is just about as good as another. All they do is distribute the weight and have no sway control ability. If you want sway control, you must add a friction sway bar to the hitch assembly. Cost of these hitches can run from $250 up to around $450. The cost of the sway control is around $75.
However, there are many other hitches that integrate sway control and weight distribution into one package. They are a step above the "standard" hitches in most cases. Some examples are:
Reese "Strait-Line" hitch (Dual Cam)
Equal-i-zer hitch
Reese "SC series" hitch (similar to Equal-i-zer)
Huskey "Centerline" hitch
Blu Ox "Sway Pro" hitch
These hitches will cost from $400 to around $700
Then there are the expensive hitches that eliminate sway altogether.
Hensley Arrow hitch
ProPride hitch
PullRite hitch
The above hitches will cost around $2500 to $3500.
