RE: Fun at the CAT Scales - Kind a Surprised at the result.

Trailer is an 2004 30 foot Airstream. The older ones (like ours) much lighter than the current model. It weighs in, fully loaded, at about 8K pounds. Here is the info with Drive Axle added. My gut tells me, it is the auto leveling air suspension creating these numbers. I disable it to set the WD. Thanks in advance for any thoughts. With No Weight Distribution applied I rolled across the scales: Drive Axle: 3660 Steer Axle: 3300 Trailer Axle Load: 7200 With first increment of Weight Distribution applied: Drive Axle: 3520 Steer Axle: 3400 (+100 Pounds) Trailer Axle: 7220 (+ 20 Pounds) with second increment of Weight distribution applied: Drive Axle: 3380 Steer Axle: 3520 (+220 Pounds) Trailer Axle: 7240 (+40 pounds)

Fun at the CAT Scales - Kind a Surprised at the result.

Hi Team, I went to the CAT scales yesterday. All loaded up for camping, the numbers were all within spec (truck and TT). Then, with the CAT Scale app, re-weighs are only $2.50, so I figured I would fool around with WD adjustments. Here is what i found: First, we tow our TT with a Hensley Hitch. The hitch has a 6 inch drop stinger. Truck is a crew cab, 6.5 foot bed with four corner auto leveling air ride. Trailer is 30 feet long. Here are my measurements from the hitch ball on the Hensley: Distance from hitch ball to center of front wheel: 18 Feet Distance from Hitch ball to between the two trailer wheels 18.5 feet With No Weight Distribution applied I rolled across the scales: Steer Axle: 3300 Trailer Axle Load: 7200 With first increment of Weight Distribution applied: Steer Axle: 3400 (+100 Pounds) Trailer Axle: 7220 (+ 20 Pounds) with second increment of Weight distribution applied: Steer Axle: 3520 (+220 Pounds) Trailer Axle: 7240 (+40 pounds) So considering these two data points. Of the load removed from the Drive Axle: 17% is going to the Trailer Axle 83% to the Steer Axle. Given my math, and the relative symmetry of my setup, I would have expected a higher percentage transferred to the Trailer Axles. I have a few other passes (with different settings) that support about 17% transfer to trailer axles. Keep in mind, this is not 17% of TW, It is 17% of what is transferred off the Drive axles. As I said, all is good with the trucks specs. Just curious what I am missing. Thoughts? Is this typical of Pivot Point projection Hitches? P.S. Setup drives great. tracks like it is on rails.
