I had a 2005 3500 dually/Cummins. I liked it, but the frame cracked where the steering gear box mounts. It started clicking when I turned it and I finally took it in to the dealer. Diagnosed the cracked frame, called in the corporate sharpies and said they repaired it. It never clicked again. I don't know where the 1/2 ton Rams are manufactured but I thought some or most of them were made at the Warren, MI plant? I know my 3500 was made in Saltillo, MEX which I wasn't crazy about but I wanted the Cummins.
Motor Trend had some good things to say about the newer Ram 1500s as well. https://www.motortrend.com/cars/ram/...year-finalist/

And that Ram would have needed a plug change at 30K miles.
It looks like they went back to Platinum plugs for the 2014 models. Prior to this....16 plugs at a dealer cost of $400.00 with installation. The deeper question is why do they need 16 spark plugs?

Diesel pickups with engine braking use an entirely different system for engine braking than over the road rigs. Pickups use several methods to throttle the exhaust. "Jake brake" equipped trucks alter valve timing to achieve engine braking. As an aside, "Jake" (Jacobs company) is just one brand, so signs posted by municipalities prohibiting their use is illegal. The signs seem to be disappearing as the municipalities are being sued for their use.

Yeah I should not have used "Jake Brake style" in a general term. Exhaust Braking may be a better choice for grade braking on medium duty applications. The end goal is basically the same......to eliminate or minimize the ability of the compressed cylinder gases to do work on the pistons. With the later being the exhaust brake which adds negative work to push out exhaust gases. I have grade braking on my gasser 1500 and it works extremely well with fuel cut, cam phasing (to increase pumping), trans shift mitigation and braking. Its really cool to hear it work with the rev matching downshifts. It however cannot compete with the diesels since compression is much lower.

I did them myself with no problem. Cost a lot less than $400.
The hemispherical design is a bit dated. It makes a TON of power because it gives a lot of space for combustion above the piston. Because of this large area, the fuel and air mixture is a little cooler, and may not burn as efficiently with a single plug, hence the two plugs per cylinder. More spark means more complete combustion which equals greater power.

Todays hemi is not a true hemispherical combustion chamber. We tried, but it had to be modified to burn more efficiently. It failed emissions miserably and as a result required the twin plugs to cut down on HC. But who really cares about emissions...it does make good power.

Wow, I don't have any of these issues with my Tundra. Also plugs get changed at 100,000 miles.
Largest brakes etc.
Its also ranks 2nd as being the most american built truck, Ford was first.

If I remember correctly (that doesn't always happen) Toyota's first 1/2 ton PU's had a lot of Ford in them. They still may.
