Any new Ram Owners?

My 2013 Ram Longhorn has the 5.7 hemi 8 speed auto with the air ride Just turned 128,000 miles Doesn't use a drop of oil between changes Runs , drives and stops like new. I've had a few issues with the air ride BUT bought the lifetime warranty and it's all been covered with $100 deductable (money well spent)
Just out of curiosity, what is the cost of a lifetime warranty.......And, what does it cover?
