Pain, numbness and tingling of the left arm may signal a cardiac emergency. Photo Credit: Comstock Images/Stockbyte/Getty Images The person walking into an emergency room with symptoms of pain, numbness and tingling in the left arm should be prepared for a series of tests to rule out a heart problem. This is not because a heart problem is the most common cause of these symptoms, but because it is the most serious of the possible causes, and the one that demands immediate medical treatment.
Tongue Weight (also called Tongue Load) is the actual weight pressing down on the hitch ball by the trailer. The recommended amount of Tongue Weight is 10-15% of the GTW. King Pin Weight (also called Pin Weight) is the actual weight pressing down on the fifth wheel hitch by the trailer. The recommended amount of King Pin Weight is 15-25% of the GTW. These weights are added to the tow vehicle's GVW.
Since this is a smaller trailer, you can measure the weight of the tongue using a standard bathroom scale. The trick is to make sure that the scale is at the same height as the hitch ball on the tow vehicle. Usually a small box or a cinder block will do the trick. Next, carefully place the tongue of the trailer directly on the scale and read the weight. This is your tongue weight.
