Upgrading to an electric tongue jack

I just replaced my cheap electric jack because of intermittent functioning, blowing fuses, and rust (a lot) in the power head. Of note, while trouble shooting the old jack, water literally poured out when I disassembled the head (no recent rain). I'm sure I could have repaired the old one, but I just preferred to start fresh. I went from a 3500 lb to a 3000 lb jack made by Barker - they are reviewed very well. It works great, and has plenty of capacity to easily get the WD bars on.
I now keep the jack head covered with a small trash can while not traveling to avoid water problems.
