Check out dually valves at Yourtireshopsupply.com (
http://yourtireshopsupply.com/catego...rd-dodge-class). Not especially cheap and require having a local tire shop dismount and remount your tires. But they are simple and bulletproof. Mine ran me $210 installed which seems a lot but seems totally worth it. Get a TPMS system too. Can’t help with the bug deflector. Maybe only drive in the winter?!
