Farmall Cub

Back to tongue weight for just a minuet. Why can't we just take the ol' digital bathroom scale, place a small piece of plywood on it, zero, crank the trailer up off the ball and get a very good idea of our tongue weight? As long as it's than 400lbs, any digital bathroom scale should be able to handle it.

You can.

I needs to be under the ball mount, not the jack stand if you want an accurate weight. A rule of thumb I use in the field is that the bumper of my heavy half Ford should be between 2 and 4 inches lower with a loaded trailer hitched then without the trailer.
