Too much or too little tongue weight while towing can negatively affect stability and handling, and can also damage your vehicle. Likewise, towing an unbalanced load can cause dangerous trailer-sway conditions. The ball and receiver from Weigh Safe comes with a built-in scale that indicates the downward force on the hitch (between 10 and 15 percent of gross trailer weight is recommended by the company). Weigh Safe hitches are available in four-, six-, eight- and 10-inch-drop lengths and in 2.0-, 2.5- and 3.0-inch receiver sizes. The product is made from aircraft-grade aluminum and high-strength steel, with pricing starting in the $300 range. Get yours at
