An electric tongue jack seems to be a very popular modification especially with the larger trailers. The idea of cranking the jack up and down didn't appeal to me and after doing it the first day we towed the trailer I could say that I had "been there, done that." The Barker 3000 offers a 3000 lb lifting capacity as well as a built-in LED light (for hooking up at night) and a bubble level. I have to tell you, being able to lift and drop the trailer with the tip of my finger is a true pleasure. A few additional pictures are available here.
