ok so full disclosure... ive done a google search and cant find my answer, im new to the diesel world and dont know much about it. I own a 2016 Ram Cummins turbo diesel 2500. My question is, should i be driving with my exhaust brake on in full or auto? is there a difference? should i only use it while towing? can i damage anything by using it or not? i have questions but no answers, please help.
