Came out to Vegas for the NFR to deliver some signs and on the pull from Laughlin saw white smoke coming out of tail pipe. Pulled over and coolant was low filled back up and smoke cleared up until I got to Vegas and then it let go. Coolant was coming out the tail pipe and tons of smoke as well. Towed to dealer and replaced head gaskets and EGR cooler. I wanted dealer to give me a crate engine but they balked at that. Truck runs good but engine temp creeps up on some grades to 225. I was only pulling 15k. I am kinda missing my LLY.
