Tongue weight/trailer weight determination


John Welte

Recommended Posts

Hi all, we left Oregon for Tennessee and I stopped at a CAT scale.  That gives three readings;  steer axle, drive axle and trailer axle.  How do you get tongue weight and trailer weight?  Do you weigh with the Anderson attached or remove that for weighing.  I saw a thing called Smart Weigh that weighs each tire, but is only available in Florida, Texas and Arizona.  What do y'all do?

3 weighs if you have a weight distribution system/Anderson anti sway hitch....there are 3 "platforms/scales" at the CAT scale

1) Weigh your TV and trailer with weight distribution enabled, front axle of TV on front platform/scale, rear axe of TV on the second platform/scale and trailer axle/axles on the 3rd platform/scale
2) Same as above but weight distribution system disengaged, I leave it attached but just loosen the tension on the chains.
3) Only TV, front axle on front platform/scale and rear axle on 2nd platform/scale.

Make sure the 2nd and 3rd weighs are "re weighs", i.e you pay full price for the 1st weigh and much cheaper for the 2nd and 3rd weigh.

Then punch the numbers into this spreadsheet.

Thanks.  I couldn't get the spreadsheet to open.  Thanks for the detailed order of weighing.

It’s an excel spread sheet, pm me your email address and I’ll email it to you, or on your phone I think you have to download it first, when you click on it look for the download prompt to pop up on the bottom of your phone?
