Sherline tongue weight scale. I keep one in my toolbox and use it every time I load up the TT or cargo trailer for a long trip. Good investment if you tow often.
Without a tongue weight scale, then it requires at least two trips across the CAT scale to determine tongue weight:
1] tow vehicle and trailer but without the spring bars of the WD hitch attached,
2] Tow vehicle with the head from the WD hitch but without the trailer.
Combined weight on the front and rear axles with the trailer minus the combined weight on the front and rear axles without the trailer = tongue weight.
But a cat scale is not very accurate for weights of only a few hundred pounds. For example, while setting up my WD hitch I have one CAT scale ticket that shows
steer axle 3280
drive axle 3520
trailer axles 3620
gross weight of 10,420 pounds
and another a few minutes later that shows
steer axle 3040
drive axle 3880
trailer axles 3480
gross weight 10,400 pounds
The gross weight should have been the same, but one ticket was without the spring bars tightened and the other ticket was with the spring bars snugged down. That 20 pounds difference in gross weight is scale difference due to the scale rounding of the weights on the three different scale pads.
You don't have that scale pad rounding problem if you use a tongue weight scale.
