Jack Cover, (John Higson Cover, Jr.), American physicist and inventor (born April 6, 1920, New York, N.Y.—died Feb. 7, 2009, Mission Viejo, Calif.), spent most of his career in aerospace but became famous in the mid-1970s for inventing the TASER, a handheld weapon that fires darts attached to insulated wires to deliver debilitating electric shocks at ranges of up to several metres. Cover’s goal was to devise a nonlethal means of stopping violent acts, such as riots and hijackings. Though the TASER was initially classified as a firearm because the darts were propelled by gunpowder, in 1993 Cover used compressed nitrogen to activate the darts; the modification allowed the public to purchase his invention. The TASER name (a registered trademark) was a modified acronym from the title of one of Cover’s favourite childhood books: Tom Swift and His Electric Rifle.

Back up your vehicle to the coupler of your hitch. Center the ball directly under the coupler (duh, right?). Lower your jack down so that the coupler connects with the ball and you raise up the jack up until it can't go up any more.  (Don't raise jack all the way up yet if you have a weight distribution hitch that requires you to lift the hitch as well as the back of the tow vehicle.)
The cover has worked great. The reason for only 4 stars is that we took preventative measures when it arrived. Many reviews complained about it leaking. We turned it inside out and sealed all the seams. Once dry, we put a plastic bag on first and then this cover. Using both has made a water/weather proof cover to protect the electronics of our power lift. The plastic on its own is not strong enough, adding this cover made the difference.
