is this worth buying?

Sherline Trailer Tongue Weight Scale - 2,000-lb Capacity
How often do you need to weight the tongue weight?

Once? Why would it change?

I guess it all depends on the type of trailer and what you're hauling. I wouldn't think the tongue weight of travel trailer would change much. However if you have a 2 wheel utility trailer it will change every time you load it. The same is true to some extent with a mulit axle equipment trailer and possibly a 5th wheel trailer.

I don't have a tongue weight scale but it would come in handy. I have a multi axle equipment trailer that hauls everything from end loaders to tractors to yards of gravel or pallets of bricks. Each load has to be thought out in advance to keep from overloading one of the axles and keeping the prpoer weight on tongue so the tow vehicle handles properly.

IMHO it changes every time you load the trailer. Depending on where the load is. more weight loaded forward adds weight to the tongue. Adding weight to the rear lessens tongue weight.

I bought one and it worked fine so I kept it. There is another method you can use to find out the tongue weight. It involves your bathroom scale and some 2x4's, a tape measure and a brick or block. I have used that and it works too and it is almost free to use. Go to www.etrailer.com and look for "determing trailer tongue weight". It's all spelled out and easy to do.
Good luck and safe travels!

I like weighing the tongue each time I load the trailer. Things like the amount of water on board, the level of propane in the tanks, how many rocks Lucy managed to sneak under the sofa, it all makes a difference.
