ThanksI'm not 100% sure on the big boy trucks, but on my 1500 i traded in, it was anything that was under 5mph considered as idle hours.
The dealer most likely left it idle lots i see it all the timeForgot to add this.
Thanks.7600 miles, 191 drive hours, 15 idle hours. Mine had 6 idle hours on it when I purchased it new with 11 miles. 2019 2500 6.4.
