I got hit in a snow storm and pushed into oncoming traffic then hit by a 60,000 lbs snow plow. Truck was totaled had to be cut out of it because all the doors were stuck but I walked away with minor bruising from the seat belt. Just got my new 2026 last week. Definitely recommend for safety and 24 mpg on the highway with the twin turbo hurricane and plenty of power.

2020 Ram 1500 Limited
Bought a 2020 Ram 1500 Limited new and owned for 4 years. The starter went out twice under !00,000 miles so replaced 2 starters, had spark plug miss fire that had to get fixed, had exhaust manifold crack making the clicking sound upon startup, gas mileage got bad around 80,000 miles. I loved my truck but was stuck 2 where truck wouldn't start because the starter Ram uses is too small and not enough power for the start/stop and this size of engine. Also, heated seats are not hot at all. Coming from a F150 where the heated seats were incredibly hot which felt great, Ram not so much.

Great experience with Carlos
We purchase a new vehicle at least every 3 years. . .so we have had quite a bit of experience with car salesmen. Carlos Lopez is by far our favorite. He listened to what we wanted; was attentive (even though he was very, very busy); and made our experience a great one. Dan handled our finances and he was a nice surprise. This is where you can sometimes feel pressured into purchasing a maintenance plans even when you had not intended to. He presented us with options but did not pressure us in any way. Refreshing. Great overall experience. You cannot go wrong with Bommarito Nissan West County. They have a nice selection of vehicles, nice facility, and as I already mentioned--first rate staff.

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 .

Beautiful, reliable, one of the best looking trucks on the road today. 5 years of ownership. Had no mechanical or any other issues, just your regular oil changes. RAM had a couple of recalls, but those always have bee taken care of by RAM. I do recommend this truck.

Good truck - package availability needs work
Love the truck But, why in the world does Ram not offer the advanced safety group (adaptive cruise, in lane guidance) and the 4 corner air suspension in after sale install kits? At this time: there are 4 - 2023 ecodiesel Rams equipped with advanced safety tech group in the ENTIRE country. There are 3 equipped with air ride. Why isn’t this more widely available?

Great Truck
Bought the RAM 1500 Laramie 4x4 about a month ago. Very pleased overall. While I knew going in it would be a gas guzzler, buyers should take gas mileage into consideration when buying. That said, the truck handles very well, is great on long drives, and interior is exceptional. Beautiful design overall

Power, beauty, and utility!
Power, beauty, and utility! Haul all week and drive to a cotillion on the weekend! I have received more compliments on this vehicle than any other I have owned, including a customized red and black striped ‘73 Mustang convertible and an ‘02 Z06. It can get up off the line or take me safely into work in a snow storm, all while looking great doing it. Only things it’s missing is a blower, a sun roof, and stereo amp. But then, if it had them, I’d never get out of it.

No question, RAM has the other brands beat!
I've now had 3 2015 or newer Ram 1500's. I tend to out between 30k to 35k per year on my trucks, and I have had almost no issues with any of my Ram 1500 pickups. The first one and the one I am currently driving both had 5.7 liter Hemis, and the middle one had the 3liter turbo Eco Diesel. The last 2 have been Laramie editions with the first being a Big Horn edition. I have nothing but high marks to give these trucks across the board. Power-great Exterior styling- great Interior (especially the Laramies) - Stellar Reliability - great I think they are easily the best value and best looking trucks on the market.

Working with Trent and the staff at Dave Mungenast was easier than I had imagined. While looking at vehicles all day, we were exhausted and ready to give up. Finally, after visiting many car dealerships, we found one at Dave Mungenast. Thank you Trent and staff that stayed after hours to help us finalize our purchase.
Great Truck
We bought the Laramie with the sports package and just love it! Also got the etorque, did not think we would like but love it too! The gas mileage has averaged around 20. Love the comfort, the amenities, everything about it, has been a pleasure.
