I looked at them, but my truck, trailer, and camper on the truck goes about 17K.You don't say if the truck bed is empty or not. The 6.4 just wouldn't do it on Colorado mountain passes. So I bought the 2019 Chevy Duramax 2500HD with the Allison 6 speed transmission.I don't do a lot of loads pulling, but it really does the job.I passed on the Dodge diesel because the Chevy has a lot more torque, but mostly because Dodge messed with their short bed length and cut it down another 3-4 ". My slide in camper was too long for it.
BTW, concerning gas mileage, I have been getting 16-18 mpg empty running 70mph and remember those 6.4's take premium gas,so you don't save anything there
