Update, after receiving NO responses I went ahead and ordered the Barker VIP 3500/24. I installed it this afternoon and other than it being reverse wired, when you press UP the jack goes down and when you press DN it goes up (unless they are referring to the trailer going up and down) it works great, and was easy to install.
We are off to Branson Landing Tuesday with our Good Sam club so will give the jack its first try.
I'm used to referring to the part that actually moves for safety reasons (no fingers or toes in the way), in this case the jack foot. But like my boat motor tilt indicator it shows the bow position instead of the motor position.
Anyway it will be nice when its in the 90's to press a button instead of hand cranking.
