That's one of the best reasons to have an electric tongue jack! I got way tired of cranking a manual jack to get the bars on years ago. It is amazing that the jack can lift the trailer and back of the truck, if the truck is at the right attitude, you almost have to lift the rear wheels of the ground to un-tension the bars. Yes the hitch comes with the tool to pry the bars onto the L bracket, but nothing to to take them off, so you have to use the jack. I think I used the tool once.
