I'm a big fan of the Level-Up system too, but there is one thing I don't like about it. I live on a sloping and uneven cul-de-sac, and have to be very particular where I park our trailer before unhitching. The system has a 5-degree out-of-level limit, and will stop raising the front when that limit is reached.
I have parked the trailer on the cul-de-sac where I needed to raise the front about 5.2 degrees to get the weight off the truck, and it stopped at 5 degrees and displayed an "excessive angle" error. After repositioning the trailer, I was able to unhitch with a 4.7 degree up angle. I have painted marks on the street to be sure it is in the right location in the future.
