No matter how you slice it the jacks are pretty close to the ground. You need to be extra careful not to let the tires leave the paved roadway.
I learned the lesson the hard way, in my first week of ownership I bent a jack mount.
Once you understand you cannot let the RV tires leave the paved surface you'll be OK.
Of course on occasion the wheels may leave the roadway, when this happens you need to ensure the unpaved ground is solid and the wheels don't sink into the soil. When wheels sink you are in trouble!
However on solid paved ground the low leveling jacks are generally not an issue
