Measuring 5th Wheel Pin Weight
Hi All,
Has anyone used a Sherline LM-5000 to measure the pin weight of a 5th wheel? If so then what is the setup you used to align the scale to the pin? Or is there some better device? After getting a scale reading for the entire setup I wanted to use this scale to check on different loading options for the pin.
Thanks,
Tim2016 GMC Denali 3500 SRW

I heard of this being used measuring tongue weight on a travel trailer...haven't heard of anyone trying to do this on a 5th wheel. Most will just scale their set-up at a CAT scale and get everything they need to know by weighing the front/rear axles and trailer axles on the segmented scale then repeating the truck front/rear axle weighing without the camper.
If you have a 5th wheel tripod you could perhaps adapt the top of it to hold the Sherline scale. I wouldn't be trying do this using the hitch in the truck which could pivot.

I thought about just using the bed of the truck with some 4x4s to build a small platform for the scale. Then use the front legs as a safety backup

Seems like a recipe for disaster. I would just weigh the truck loaded and then unloaded, the difference is the pin weight.

I agree with using an axle weight scale at the truckstop, just weigh empty and loaded and some simple math and you have your answer. Hitched up you know you are safe, anything else may be a recipe for disaster...

What do you do when you don't have a scale near by. The closest one to my house is over an hour away so not really useful for a loading experiment.
Anyways I found the manual for the Sherline - http://sherline.com/Wordpress/wp-con...1/lm_book2.pdf where they listed the following for a 5th wheel:
For 5th wheel trailers, the Sherline™ scale can be blocked to
the proper height directly behind the hitch on the bed of the
truck. With the trailer supported by the trailer jack, move the
truck forward until the kingpin is directly over the scale. Lower
it into position with the trailer jack until the full weight of the
trailer is on the scale.
Note: Because of the large variety of available 5th wheel hitch
designs, some ingenuity may be required on your part to safely
support the kingpin on the scale.
I am using an Anderson hitch so it should not be a problem to align the scale with the kingpin coupler and use the bed of the truck as noted above. I'll keep you updated.2016 GMC Denali 3500 SRW
