an issue I have had with the one touch level up:
When the jacks are near are at full extension, you will get an error message. Not a huge issue with the front jacks but when it is the side jacks, the computer starts doing funny things with the front jacks and you start scratching your head. My advice, is, when you think you might be at the limit of your jack travel place a piece 2x6 under the foot. It is easy to get lazy with the one touch level up. You pull in, park it, push the button and break out a long neck. I like the one touch level up system and so do the other guys who watch how quick I get to the beer.
