Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Great service at J Star Dodge
J Star Dodge has the best customer service of any place of business I frequent. They have been the only place I use to service my 2019 Dodge Durango. I have 69,200 miles and it runs like it’s brand new.

I walked into Wheelers Chevrolet and Connor greeted me so
I walked into Wheelers Chevrolet and Connor greeted me so politely. Told him what I was interested in as We sat down at his desk. He offered me a beverage. He took me for 2 test drives, a z71 2025 new traverse, and a LT traverse. Connor was very knowledgeable and answered any questions I had. My husband was not with me. I made an appt to bring my husband next day. We did test drives and picked the the Z71. No pressure at all like some dealerships we have been too. Everyone there were so friendly and knowledgeable.. Cody took our info down for the finance aspect. Very professional and knowledgeable. The paperwork went very smooth. We will always go to Wheelers as our experience was top notch.
