Where to weigh trailer tongue?

Hello,I took my trailer to a Flying J and weighed both trailer and truck together and separately. However I also tried to get the tongue weight and the scale would not register the weight, too light I guess.

Any suggestions for weighing the tongue?

Thanks!

    If you post the weights which you did get --
    we may be able to calculate a good estimate of tongue weight from those values.

  • I have used the bathroom scale method on both my TT and my boat trailer and once I did make it to the scales found it quite close. Close enough for my purposes. A trip to the scales is worth the time and money though.
  • The "bathroom scale" method works well. I have done both (tongue scale and bathroom) with a cheap bath scale ($10 - plastic body, etc) and it was within 20lbs and that's not even using a "exact pipe" technique... just 2X6 "beam" and 2X2 "fulcrum points". Tongue "weighed" in at just under 600 lbs... ie about 190 on the bathroom scale.
  • There is no more accurate way to get the tongue weight than the CAT scale!

    How heavy is the trailer that you are weighing?
  • If you weigh the truck by itself and then weigh it again with the trailer attached then the difference in weight of the truck would be your tongue weight. That's the way I have always done it. The CAT scales are in sections and very easy to do.
  • A bathroom scale? No kidding!! I'll have to go to the link and see how that works.

    The weight should be over 300 lbs. The trailer weighs 4500lbs. It tows just fine but it would be nice to know.

    Thanks, you guys are extremely helpful!!!!!
  • If you think the tongue weight is under 300 lbs use one bathroom scale with piece of thick plywood on it.

    Or if over 300 use two bathroom scales with a board between them to place the tongue on.

    Add the weights shown together and subtract the board weight. This will give you a fairly accurate approximate to use.
