Nice Tongue Jack for my RV. It installed in Minutes and I tested it. It cranks easily and will get the job done.Since I live in the Pacific Northwest near the Ocean,it rains alot.The Electric Jack went haywire after 2 Yrs.It looked like it was a sealed unit,but when it quit.I took it appart and found it had at least a cup of water that came out of it.Hence,the Switch was Shorted out.I was very disappointed since it was a top of the Line Lippert Jack.Problem Cured with this New Hand crank jack.And I will get a little exercise too-boot.Thanks Vevor.
