We had a hand crank jack on our 17B, and Anderson WDH. That made for a *lot* of jacking up and down every time we hitched or unhitched, which we did for a full year of trailer habitation.
We ordered an electric jack and the E2 on our 19, and love how much faster, easier, and less sweaty the whole process is. Especially if you happen to roll into a CG as it’s getting dark and cold rain is flying in your face. Well, the dark, cold, rainy scenario isn’t normally sweaty, but I’m sure you get my point.
Love the electric jack.
