Yeah, no way I'm cranking that thing in the S. Texas heat. It's miserable enough just being outside in August, let alone doing manual labor.
If I can help it, I will never own another manual tongue jack; power all the way! If they ever break, I'll always replace with power.
I just mentioned the TV jack as an emergency "field repair" that might get you out of a sticky situation if you were to experience a catastrophic failure of your power jack. You most certainly do not want to make that your SOP.
