Stock 21 Overland with tonneau 18mpg on 87 , 19mpg on 89. Mostly in town driving 30-50 mph. Highway around 22mpg 65-75 mph. Much better than my last trucks avg of 11.5mpg!
I installed my mopar trailer brake on Saturday, and hooked up to my dump trailer today for a test ride. The brake worked great with no warning lights or codes like some people report.
