I bought my first 2018 duramax, always pulled our 13k 5er with a 6.0 gasser, no real issues other then it was always at about 3k rpm now with the duramax its always around 1800-2000rpm. I am Very dissapointed in the mpg tho, the gasser would always get 7mpg and the duramax only gets 9 mpg, I was expecting far more then a 2 mpg gain for the additional $10k I spent
