I am a person that gets so stressed just thinking about
I am a person that gets so stressed just thinking about car dealership. Crazy cheap cars made it so easy. Was not stressed at all we worked with Tony he has honest. Help through the whole process no pressure. It is nice to have someone help me feel comfortable with my decision. Tony is down to earth, felt like family just talking with him. You can't go wrong with Tony. ❤️
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

1st car loan
Picked my truck up today did take some time to get everything arranged but well worth it I did request that i wanted a new set of tires before I picked it up and that was not a problem. love my truck will write a follow up review after a little bit.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

They had the truck that I was looking for. Jay, my Salesman was great. Took the truck for a ride and there were a few issues that needed to be taken care of. He got that taken care of with a price that I purchased the truck. I would Highly Recommend in purchasing a vehicle from Orleans Ford.
