Chevy and GMC Duramax Diesel Forum

This is pretty much how it looked when I picked it up. Gonna start one of these things called a build thread. Bought the truck in Tremonton UT. From a small dealership who bought it at an auction earlier that summer. It was bone stock as far as engine was concerened. Came with 20" Foose chrome wheels... 1TRIKHD Victory Red CCLB

I'm so tired of people saying.... "No way those are 30 mpg trucks!" Common comments are "You are coasting down hill", or "You have a tailwind", or "You are driving like Grandma......" Uhhhhhhhhhhhh......no. I went from Aliso Viejo to Tucson AZ this week. Non-Stop, with two hops off the freeway for the Jack in the Box Drive Thru and stopping to down some taco's, and right back onto the freeway. About 7 hours, 465 miles in total with two 15 minute food stops. The results? [ATTACH... 30 MPG LZ0

My DEF tank is full but I have a message stating it's empty with xxx miles to max 65 mph. I replaced the DEF pump/heater a couple of years ago. Does it sound like it needs replacing again? Any testing suggestions? 2017 with about 200K miles

I've never had the time to sit down and actually put all this into anything other than a random post on Facebook or Instagram. I'm going to do my best to recollect everything since the beginning and find the appropriate photos that I've scattered across the web and hopefully piece this journey together. I can't promise to wrap it up with a nice little bow, but I'll do my best.

Had one crack and looking to buy a single used or new replacement.

Hello All, I am hoping you may know some areas to troubleshoot. My AC will blow warm and back to cold intermittently while driving. When it kicks on, It has the smell of when an AC unit first comes on then will cut off again often when truck is at idle. If it is hotter outside it is often times hard to get it to switch to cold. I when it is cooler out, it seems to kick into AC quickly. Here lately, it is over 95 out and the AC will click off and on while driving. Other details 1. Seems... HELP, AC Keeps blowing warm
