We seem to have developed a new issue on our new Landmark. We were laying in bed watching TV last night around 9:30 and heard a pop that sounded like it was right under us. We kind of looked at each other but my first thought was the LevelUp system. It happened two more times in a 15 minute period. I finally got up and went out and re-leveled the trailer and we did not hear the noise again overnight. I did not do any checking or trouble shooting as I had to be up at 4:30 am for work. I have read the LCI manual "Adding anti-stiction fluid to LCI Hydraulic systems" in the HOM but can't imagine this would be the issue since this was put out in July 2013 so one would assume they do that no before any unit is shipped. For right now I am just going to watch it and see if it happens again. My wife is beginning to think we made a bad choice with this trailer.
