A second trailer jack I'm considering (see my original email below) is the DL74MR. What is the weight of the DL74MR to the nearest tenth of a pound? Original email: Mike C. 8/17/2025 What is the weight of the DL22507 to the nearest tenth of a pound? I want to carry one on a motorcycle to help pick the heavy bike up when it falls over, but I don't want to carry anything very heavy. Thanks.
