Versatile and comfortable hauler
This SRW truck carries a slide-in truck camper and tows a boat when it's not a daily driver. The gas 6.0L is very capable to handle both and the truck is comfortable riding when not loaded down. Reliable engine and truck.

Jessica is the nicest and honest sales person I have ever had! Very knowledgeable and helpful. Dave Q the Sales Manager is honest, knowledgeable kind. No pressure and took very good care of my husband and I. 10/10 I recommend!!
Great truck
This is a very clean, serviced and useable truck. I "live" in my truck and needed reliability, but without the garish price of new. All my tools fit and it is very handsome interior and exterior.

The experience with Leanna Tabora was great.
The experience with Leanna Tabora was great. She helped me from my initial request on the vehicle and walked me through the trade in perfectly. Given that I was in San Diego, I was not sure how the trade would work out but everyone and dealer followed through with their commitment. Oscar with Finance was great got me in out within about 20 minutes. The entire transaction took about an hour and a half from when I arrived with my trade in vehicle.

Sebastian was very helpful and after some negotiation we settled on a price we both agreed on. I had to drive almost 3 hours to go get the truck from him and I’d do it again any day. If you’re buying a vehicle from Greco Ford ask for Sebastian because he topped my diesel off and detailed it for me. Great experience 10/10.
