opinions on 2012 RAM 2500 5.7 gasser

Anyone that had performance issues, didn’t have the proper setup for towing!.

I'm more than pleased with mine. It has more than enough power to pull my 5th wheel up any grade that I've come across in Alberta or BC. Loaded is about 9000 lbs. It has a 4.10 rear end and I get between 11-13 MPG (Imperial). The only issues have been a front axle seal and broken exhaust manifold bolts.

Ask yourself why they are so cheap? Had a ‘14 and it was the worst vehicle I have ever owned. Apart from the near monthly recalls it was always in the shop. I got rid of it after a year and a half and 4 transmission rebuilds, rusty chrome bumpers, leather seats falling apart, failed power mirrors, and numerous electrical and radio problems. Resale is poor and I even got turned down by 2 dealers who wouldn’t take it on trade.

The 5.7 is a proven engine but the 66rfe transmission is a poor match. Large gear spacing causes the engine to bog down as it’s always in the wrong gear. Google it and you will see lots of complaint posts. Several times I was unable to accelerate out of 1st gear pulling hills with my 7600lbs tt. Holding hwy speed was usually 4th gear. I could get 5th downhill with a tailwind. Truck had 3.73 rear.

The only reason I have another Ram (diesel) was because of the sale incentives, full warranty and they took my trade. Time will tell if I keep this one beyond the warranty.

Solid engine and trans (assuming it's an auto). The 2012 was still the old chassis. In 2013 (3500) and 2014 (2500) all the underpinnings got beefed up substantially. Thinker parts and a higher GVWR/Payload.

Aunt has on just like your asking about, pulls 10k from Ohio down to Fl and all around other states. No issues, she doesn’t complain about it, good truck, plenty of power and so far reliable.

Very capable vehicle. What do you plan to do with it? Check the door sticker for towing and payload capacities.

It'll be fine so long as you don't want to pull a heavy load.
