About the 5th-Wheel Trailer Tongue Weight Scale
We made this scale at the request of several of our customers who own fifth-wheel trailers. This scale is a modified version of our original Trailer Tongue Weight Scale. However, it is specifically designed to attach to most fifth-wheel trailer hitches. The piston has also been modified to accept the standard 2-13/16″ diameter kingpin and the locating pin is for hitches that accept the standard 2-13/16″ kingpin.
The scale uses a simple hydraulic principle to convert pressure into a reading in pounds and kilograms on the gauge. No delicate electronics, no batteries, and only one moving part. It comes with a 5000 lb. gauge since 5th-wheel trailers typically carry a larger percentage of the overall weight on the hitch.
The scale is machined from solid billet steel and aluminum. It has a 3.25″ piston and body diameter, a 6″ square by 1″ thick aluminum base, and is about 6″ high. Actual weight is 11 lb. Gauge diameter is 2.75″. This scale comes with a one year guarantee.
All gauges have a dual-scale gauge that reads in pounds on the outside of the ring and the kilogram equivalent on the inside. This feature has been requested by many trailer users outside the USA and has now been incorporated into all the scales. The 0-5000 lb gauge reads to 2250 kg.
NOTE: When you receive your fifth-wheel trailer hitch weight scale, the “locator pin” will be screwed into the top of the base for ease of shipping and storing. Unscrew the locator pin and screw it into the center hole in the bottom of the base as seen in the photo above.

Avoid Trailering Disaster!
If you tow a fifth-wheel trailer behind your truck or SUV and don’t know for sure if the hitch weight is within the recommended range, you could be headed for a disaster. Too much weight and you could damage the hitch, causing fractures in the support frame and a catastrophic failure on the highway. Most fifth-wheel trailer hitches that are installed have a weight capacity that exceeds the weight of the trailer. Where most people get into trouble is when their toys start to get bigger or their load increases as their trip around the states continues. The trailer and load that you started with was fine. It’s the load that you end up with that becomes the problem. So, how can you be sure that you don’t have excessive weight on your hitch?
To properly load and balance a trailer you must KNOW what your king pin weight is, and the Sherline fifth-wheel trailer hitch weight scale offers an easy and inexpensive way to find out.
