Question: 

What does a weight distribution hitch do?  Do I need one? 

Answer: 

With bumper towed trailers, it creates a problem if there is too much of the weight on the rear axle of the tow vehicle.   Weight distribution hitches move weight to the front axles to help with steering and braking.   While traditional WD hitches are either ‘loaded’ or ‘unloaded’, the Continuum uses a pump to allow you to fine tune the amount of weight you are moving to better control your towing experience.

Weight distribution ‘rules of thumb’:

The need for a WDH is usually mentioned in the tow vehicle owner’s manual. For instance, some trucks require weight distribution for any trailer over 5,000 lb.

If your trailer’s weight (GTW) is more than 50% of your tow vehicle’s weight (GVW)
If your tow vehicle sags when you hook the trailer to it
If you find it difficult to steer or stop
