I had a Lippert jack on my 20-footer that failed after just a few months. I now have a Barker that I am hoping will be better, but I've only used it a few times. I like the features on it better. The power jack makes in MUCH easier to deal with the Equalizer hitch because we usually have to raise the tongue - and the back of the truck - a lot to get the bars on.
