Adding electric jack?
I have a 20' tilt-bed trailer from Kaufman. How hard would it be to replace the manual crank jack for an electric one? I assume (possibly incorrectly - that's why I'm here!) that there is power from the 7-way connector that I could use to do that? Or maybe the wiring isn't robust enough to handle the load? My main goal is to get rid of the turning radius of the crank so I can put a toolbox up front. But it would also be nice to not have to crank it...

If you have a modern truck like my 19, you won't get any power from the 12 volt battery charg wire unless the truck sees 12 volts. If any of my trailers that have batteries are under 12 volts I get a trailer charge fault message. Our 12, 16 and 17 F550's and 22 F450 at work are the same way.

I agree with others, direct wire to a battery. If you do not have battery on trailer, you might need to add a connector, then run a line all the way to under the hood for best performance. This should work fine. Is this a pick up ? I have a jack like this on my travel trailer, I added, if I had a do-over, I'd find a jack that the head rotated on because my tailgate just barely does NOT open when hitched, and if head rotated 90 degrees, it would.

Thanks for the info guys. I think I will add a battery to the trailer (it has gravity tilt) and put a solar trickle charger to keep it fresh.

Isn't your trailer already wired for the 7 pin to charge the battery when you are driving? The 7 pin charge wire should have
12v once you hit the brake pedal and put it in gear or some other such nonsense. Just wire the trailer battery to the
electric jack and you should be golden. That it how it works on my Intech enclosed trailer.
