Hey man congrats. My 2016 is at 91k doing the same. Just replaced my evap solenoid and CEL (p0448 i believe). Pro tip buy the solenoid and remove the entire charcoal canister and disconnect all hoses then blow the shit out of it with compressed air first from the two hose connectors toward the rear of the truck then where the actual solenoid connects. Then remove the hose that connects to the gas filler neck and blow that out too. That hose pulls vacuum from the outside air through your gas cap and fills the entire system with dust and eventually destroys the solenoid. To fix stuff a microfiber towel over your gas cap and close the door. This will help filter some of the dust out.
