A couple of things about torque wrenches. I believe I read that the accuracy of a particular wrench is within say 20% and 80% of the range of the wrench. If you are checking the torque on your trailer, 120 lbs and also your TV, mine 140 lbs, then the wrench should be rated closer to 200 lbs to get accurate torque. Also, if I remember my high school physics, regardless of any twist on that extension, if you apply 120 lbs on one end, the same torque will be consistant the entire length. Just had to throw that out there.
