My 1500 has 90k and over the last year or so has had some significant issues with the air suspension previously lived in TX and now live in PA). I have taken it to 2 dealers and neither can seem to figure it out. Have others had this issue? I have run out of patience and feel like I just want to sell it to get it off my hands. Has anyone replaced the air suspension with normal suspension? How complicated is that and what is the cost? How does it impact the value when you sell it?
