2021 GMC 1500 SLT w/LM2 Diesel
New member here, I've owned nothing but GMCs and Chevys for the past 25 years. Last week picked up a 2018 GMC DMax 3500 to pull a 5th wheel, for when we take that step next year. This is step 1 in making that dream happen for us. I wasn't planning on buying it just yet, but I know that I wanted one just like this, and my dealership (bought 3 trucks and 1 car from them) got this one in with 45k miles on it that they picked up from a large RV dealership, when the previous owner traded it and their 5th wheel in for a Class A. I ended up getting a great deal on it, and it runs smooth as silk. I've driven duallys before (long time ago) but I was really surprised at how smooth the Allison 6spd moved through the gears, and also how tight the turning radius was. I was really apprehensive about making a dually my primary vehicle, but this thing is really great. This is my first diesel ever though, so I've been on here reading up on DEF, fuel filters, and other things I need to stay on top of now. I've had all the typical used truck fluids and filters changed at this point, as well as having it certified for the 100k mi. bumper to bumper I got in the deal. I think I just need to get some windshield time at this point to get really settled into it. If there's any other first timer tips that you guys have I'd appreciate it. Thanks!
