Do you have jacks? My Red 340 33AL has airbags exclusively. I've gotten that alarm before. I carry a 4 ft level with me in times like these. If I get the excessive slope, I'll try and check the site with my level. Of course that doesn't work if it is all broken up or uneven gravel, but it gives me an idea otherwise. I also look where the airbags are, and it is usually obvious one side is lifted much higher, hence the alarm. So far, after my checks, it was my eyes playing tricks on me. The leveler was correct. I then go back to Travel mode, pull forward or back and drive over my rubber pavers to give it a lift on that side.
