Great car for work!!

Comfort, ease of driving, style, convenient for work and we LOVE the tailgate! Great for towing our heavy fifth wheel and our dogs are riding in style!!


Great luxury ride with great pulling capabilities.

The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.


Really impressed with the performance

Nicest truck I have ever owned preforms great with my RV Truck is comfortable and still works great when you need it to preform. Ride is nice and very roomy for all that want to travel with me
