Tongue Weight Part 2 CAT Scales
Hello and thanks all in advance! So I went to the CAT scales prior to my long Yosemite drive and gained some numbers. I was able to gain a 3 different weights, trailer alone, truck alone, and th...

My method is
1) Weigh the entire rig on the three pads of the scale: truck steer axle - truck drive axle - trailer axles
2) Weigh the trailer hooked up to the truck with the two trailer axles on separate pads and the truck not on the scale
3) Drop the trailer and weigh the truck alone.
Last week it was
#1 - Whole Rig Weight
Steer - 3,600 lbs
Drive - 6,040
Trailer - 8,870
Total = 18,420
#2 - Trailer on truck pads
Steer - 4,740
Drive - 4,080
Total = 8,820
#3 - Truck only
Steer - 3,935
Drive - 4,340
Total = 8,275
When I dropped the trailer - the weight on the rear axle of the truck is 1,700 lbs lighter, however the weight on the front axle of the truck is 335 lbs heavier. This tells me the tongue puts 1,365 lbs on the truck.
(The rig was front heavy for the 80 mile trip. I had a near full tank of water, and had not dumped a nearly full black water tank.) (There is always a slight weight difference between the weight of both trailer axles on the same pad and the two trailer axles on separate pads of about 30-50 lbs which I guess is variance in the truck being dead level or not level when it is not on the scales.)
I calculate the total trailer weight as the difference between the total weight of the total rig, minus the total weight of the truck alone - 10,145 lbs.
An 'alternate' tongue weight figure would be to take the total weight and subtract the trailer axle weight - which gives the same 1,365 figure.
