"2500HD Denali 4WD. I got very lucky-snapped up this baby before it was well advertised. The previous owner kept her clean and neat and I’m trying to keep her that way. I pull a 25-ft RV with no problems. The backup cam screen puts me right on target to load, and the extending mirrors are a huge help. She sits high (good for river crossings) but is a royal pain for adding DEF under the hood up close to passenger side. Truly will make you wonder about other brands when you’re perched on an upside Down 5gal bucket trying to get that DEF hose down a rabbit hole whilst balancing the DEF BOX. Could be a comedy show! Overall I love the truck : roomy, comfortable appointed, well-appointed. Powerful with good pickup on the open road. "
