Fifth-Wheel Pin Weight Is Essential To Stability And Control

PPL Motorhomes knows that towing a trailer of any kind can be a stressful task at times for both newbies and seasoned RVers. One of the most important factors in towing a fifth-wheel is understanding how hitch weights can effect the stability of both your truck and your trailer. Larger hitch weights make the truck itself heavier, but less agile in abrupt maneuvers. It is recommend that fifth-wheel pin weight should be in the range of 15% to 25% of the trailers weight. With the center of gravity more forward, the trailer itself is more stable with a higher hitch weight. With lighter hitch weights, the center of gravity is located closer to the trailer axles and this makes the trailer less stable. However, with a lower weight the truck is more agile. This isn’t necessarily a good thing. You see, the combination of a more agile, lighter truck, and a less stable trailer can actually cause the trailer to skid and swing widely and possibly jackknife.

In the simulation in the video below, they show a double lane change at 65 miles per hour. This essentially simulates an accident-avoidance technique where the driver temporarily enters the adjacent lane and then returns to his original lane. This simulation was calibrated at just s 3% pin weight.

This is something that need to be thought about when you are purchasing your first consignment RV. You have to get the ratios right, or you could end up in a nasty accident. Give PPL Motorhomes a call and we can help you figure out the math, it’s not really as difficult as it sounds. We just want you to be as safe as possible so your RV adventures are filled with wonderful memories and not near accidents.
