Use to crank all jacks with an 18 v drill but with the heavier trailer it wouldn't cut it to jack it up to get the trailer off the hitch. Upgraded to a corded 1/2 inch low speed high torque drill. This beast will make the tongue jack work with this mod. And will be even better when I hook up an inverter off the battery to run it.
Wouldn't it be better to replace the tongue jack with an electric one? That was one of my first "mods".
