CAT scale weights

Here are my CAT scale numbers as the dealer originally set up my equalizer hitch. Note that I had NO sway issues, NO porpoising issues, NO bouncing issues, no issues at all with this set up in over 2000 miles of towing. However, my over cautious nature impelled me to visit the scales for the true story. I found that I was transferring a minimal amount (80 lbs) back to the front axle even though the fender measurements per the equalizer instructions were correct and the trailer was perfectly level.


Truck only:
Front axle 3460
Rear axle 2660


Truck and trailer with weight distribution off:
Front axle 3100
Rear axle 3820
Trailer axle 3960


Truck and trailer with weight distribution on:
Front axle 3180
Rear axle 3600
Trailer axle 4040


So, after adding 2 washers here are my scale numbers....

Truck only:
Front axle 3420
Rear axle 2660


Truck and trailer with weight distribution off:
Front axle 3080
Rear axle 3780
Trailer axle 3960


Truck and trailer with weight distribution on:
Front axle 3400
Rear axle 3320
Trailer axle 4120


Measurement of front fender through the center-line of the front axle:
Uncoupled: 37 1/8"
Coupled with no WD: 38 5/8"
Coupled with WD: 37 3/8"


After adding the washers the trailer is about 1/2 nose high. Is this/will this be an issue for me? In the limited amount of driving (40 miles of interstate) I was able to do after the adjustments today there were no issues, sway or otherwise.

Those numbers are about as close to perfect as you can get and point to the importance of going to the scales after you get the adjustments close by measuring the fender gap. I can't imagine the half-inch high being a problem, I don't know if lowering the hitch on the shank to correct this may create more problems than it solves.

Almost impossible to get closer than 1/2". With no problems towing you should consider a prayer of thanks!

I would leave it as is. You look to now be set up pretty darn well.

Thanks for confirming my weights/measurements. We are leaving on a 2,000+ mile trip in a couple of days. It will be interesting to see if there is a handling difference with the Equalizer adjustments. I also look forward to monitoring the trailer tires with a newly installed TST507.

Congratulations! You have a very well balanced setup and it will be worth all of the time it took to get it there. I kept playing with my Tundra and toy hauler until I got it very close like yours. It drove extremely well. Even though you are probably very close to optimum, I suggest you still take your loaded rig to the scale one more time. This time after getting all of your axle weights, back up and weigh just one side of each of the axles. The weights should be close to one half of the total weight for the axle. This ensures that you do not have one side over loaded. For me it was moving the two quads just a little to really balance up the load. I just replaced the Tundra and so have been working on getting it all synced up again. The public scales are closed to trucks enough that I have been able to play around with different preload on the bars while sitting right on the scales. Have a good time out there!!
