So I've had my truck since April and I have got just over 50,000 miles on it..have had issues with it that I have seen on this forum and they have been addressed and repaired..except one..the air bags are not even..my left side keeps more psi in it than the right..it varies between 1/4 to 1/2 inch in height...loaded or unloaded..doesn't sound like much but it is noticeable in my rear view when pulling the trailer.. dealer can't figure it out.. already replaced the r/s levaling valve..any ideas??
