The wheelbase is the distance from the front of the axle to the rear axle of the tow vehicle, and very important to the control and stability. Having a longer wheelbase on your tow vehicle will give you less of a chance of the trailer weighing down the rear axle and lifting the front axle.

What wheelbase is best for towing?

The longer the wheelbase, the less likely that the weight of the trailer/boat will push down on the rear axle and lift the front end. A longer wheelbase also has the added effect of providing more control over the rig. As a general rule of thumb, the first 110 inches of wheelbase allow for a 20-foot trailer.

Is shorter wheelbase better for towing?

The biggest factor to consider when towing a long trailer with a short wheel base tow vehicle is trailer sway. There is no standard ratio for wheelbase to trailer length, but the general rule is a longer trailer and a shorter wheelbase will increase the severity of trailer sway.
