I looked around for a 3.6 initially when I truck shopping but couldn't find one for under $40K here in Ontario, CAN. Decided on a 5.7 SXT instead for $20K despite the higher fuel use as I truly don't need the 5.7 as I do light property maintenance. I've overloaded the truck a few times, although not intentionally and I still had decent suspension travel but I don't tow over 3000lbs and most of my driving is in town. The 5.7 is a great engine above 3000rpm but 'feels' like a V6 below that speed. I had a 3.6 2012 200 with the 6 speed auto and it was almost too much engine for that car, hence why I was looking for a Ram 3.6 back in 2014 but it was a new combo then so prices were at a premium unless I ordered new.

Doing everyday maintenance on the 3.6 is a breeze. I haven't touched my 5.7 yet as its still under warranty but changing 16 plugs every 40K vs 6 plugs on the 3.6 every 100k is a definite savings in maintenance as well as at the pump. I average 18L/100km which is better than my old 5.9L Magnum and the 5.7 is a nice engine on the highway when wrung out, but relatively lethargic getting off the line. So far the 5.7 hasn't given me any trouble, but when I had the 200 3.6 I was given an extended warranty on one of the engine heads due to some issue at the factory but I sold it last year due to a slew of other problems (flashing dash lights, ripping back seat along two seams that was seldomly used, transmission shifting irregularly, and a few other quibbles that happened just after the comprehensive warranty ended but zero problems with the engine. The 3.6 pulled from 2000rpm+ and I think it has much better flexibility than the 5.7 despite the 2.1L difference in displacement.

As I buy trucks for work, I don't find the need to modify anything although I would look at getting deeper gears, 4.10 at least if the front axle can handle it on the newer 3.6 trucks despite the 8 speed trans having a fairly low first gear.
I have a 3.6L Durango and a 5.7L Ram, both with 8 speeds. I very much disagree that the Hemi feels like a V6 below 3000 RPM as the most noticeable immediate difference when switching between the two is the greater amount of low end torque the Hemi has-and the Durango has a 3.45 diff ratio compared to 3.21s in the Ram. I am willing to bet your perception is attributable to the 6 speed in your Ram and the much lower gears in the 9 speed in your 200.

Pentastars produced in 2011 and 2012 had a recall due to heads warping that was resolved in 2013 and from what I can tell has not been an issue since. I have heard of it happening on a couple Rams, but only very early 2013s that had V6s in them that were produced in 2012. Once most of the 3.6L Rams were in production this issue was resolved with the new heads so I would not be concerned about it if looking at a V6 Ram-though I would get a 2014 or newer since they have the 845RFE transmission instead of the 8HP45.

I have a '17 with the 3.6 with 3.21 gears and I tow an approx. 3k pound 15' camp trailer decently. This is with 37" tires/20"s and 4" lift. I could use the 3.55 gears for hills but I can still maintain highway speed/traffic no problem without.
All things considered it was about $5k for the hemi so in that case I don't mind no having it! I would do the gear swap if I went up to a bigger trailer before I upgraded motor. You gain 3,000lbs of towing capacity with just the swap!

I also have a Ram 1500 with Pentastar. 3.55 gears. I’m planning on installing 4 in zone lift with 35in tires. I also want would like to run 33s but the shop said it would look funny. How did 37 effect your power and mpg? Thanks,Randy

I average 16 mpg on highway w/o trailer.

I average about 10.5 mpg when trailering on highway.

I average about 11 mpg around town unloaded.

The truck does not feel underpowered (my other car is a 2018 corvette for reference and my RAM gets out of its own way still).
The best mod I did recently was a Pedal Commander (PC31). The 'feel' is VASTLY improved . I would never go back to driving without it now. Highly recommend.

The one or two times, you really "need" the power of the hemi are the one or two times you regret, not to have it. And it will nag on you, till the next truck is due and you will get a hemi.
I thought the same way at my first truck and thought- the 4.7 is good enough. Then we had the camper and even my wife said: we need a bigger truck.
I'd rather have it and don't need it than otherway around.
Actually, the Hemi is the perfect size for this truck. not more needed for what it's built, but also should not be much less.
I'd rather take a lower trim level for the same money but have the hemi, than buying nice and have the V6. Once you're not happy with the engine, nothing in the vehicle - not the nicest what not's- will make you happy. You will always crave.
