My driving experience with 2021 classic Ram
I bought a 2021 classic 1500 4x2 quad cab with 5.7 Gas engine. There were 2 rear differential axle gear ratio options, mine has the “hiway gear” but the truck pulls with plenty of power, I think most had that gear for fuel economy. I don’t like the idea that if I open the drivers door while in motion , a transmission brake applies and abruptly stops the vehicle. I was parking in a very tight spot and cracked. The door open and to my surprise, , the truck jerked to a sudden stop. I personally do not care for the dash knob to select the gear, it’s another electronic component that can fail, which in fact has failed . in other trucks. The 5.7 Liter engine was designed with the oil filter to be very difficult to reach , almost as if designed ‘outside ‘ the chassis without realizing once ‘in’ the chassis, the oil filter became extremely difficult to reach to replace .

We were happy with the service and time it took to complete our purchase. A sales rep (Jerry) worked with us over the phone and had many documents ready to go and prior to our arrival.
Laramie lover
Spend the extra money for leather and heated and cooled seats . It’s well worth it . Have loved my Ram after upgrading to a Laramie from a 2008 Ram st . Back seat has plenty of room . Seats fold up to allow you to put groceries in .

I had an issue with my 2021 Silverado, spoke to several employees and management, they ended up resolving my issue and took in my trade and offered and 2025 with discounts due to the situation at hand. Uri was amazing in the process of it all on going back and forth trying to get a resolution for me and closing the deal and making sure I had what I needed this time around, Jeff as well was great on assisting and bringing down the truck for me to see before I purchase due to my crazy busy schedule. Gabriel in Service as well was very helpful and followed up. I will definitely continue doing business and recommend this dealer and their staff.
