Okay, thanks for all the replies everyone!
Just to clarify a few things. I know on paper that a v6 with 269 torque doesn’t sound like the right vehicle for this load and from the responses so far it looks like it probably isn't. But as Ramzaq showed with his link there are some positive towing reviews for this vehicle. And no that is not just flat ground in his video. They towed on the Davis Dam Grade.
Here is another positive video. This guy claims he’s towing a 7,900 lb fifth-wheel with the V6 Pentastar with 3.21 gear ratio. He doesn’t start talking till about 1:28 into the video:

On the other hand this video from TFL truck is not so positive, but unfortunately it doesn’t specify the gear ratio or transmission:

Also, I don’t have the the trailer or the truck yet. I was forced to put something in my profile when I signed up. I’m looking to purchase both. The Quad Cab Pentastar configuration is my favorite RAM 1500’s because it has the highest payload capacity, low initial price and great mpg when not towing. If it won’t work, I’ll probably get the new Ford f150 2.7 Ecoboost instead. I’m not really interested in a Hemi or Ecodiesel because of the lower payload capacities.
I will be pulling on mostly flat ground and rolling hills; although I will occasionally encounter mountains.
I’m really hoping to hear from more people who have actually towed with the V6 Pentastar with 3.55 ratio. Can anyone recommend another section of this forum or another forum to possibly get more views from Pentastar owners?
Oh lort.
Sorry.
ok- the one pulling a 7900 pound fifth wheel with a 1500 V6- sorry- no comment.
I did not see on the video, how they pulled the 5500 pound up the hill- for me, the video showed a flat road- they can tell me everything- I'm a show me guy.
with the payload has nothing to do with the engine-configuration, it has to do which trim you have. Also if your first goal is to pull a trailer, then you will never exceed the tongue weight with a 22'. never. and you will still have enough left over to throw all the stuff in the bed you need. no matter which truck.
Also- 10mpg with the load they showed- well- it always depends- I am pretty sure, the Hemi would had pulled the same load with 13 or more mpg. I even get more with my camper and around 6500 pound- 12mpg.
you forget one thing- with a weaker motor you have to step on it more to reach the same power. means- the 25mpg they talking about are flat rolling in 8th gear with no wind from any side. I would say- 22 are more realistic. and there we are- I drive the hemi every day 75 miles and have a fuel mileage of 21mpg. 70mph cruise control.
then you talk about the 2.7 ecoboost (not even the 3.5 ecoboost). what you're trying to accomplish? I can tell you somebody who has the 2.7 ecoboost and he had a camper with around 6000 pound. he sold it and bought a RV because the truck couldn't pull it and he could not sell the truck because nobody wants a truck with a lawn mower engine.
I know sometimes money is a factor. In my case- I knew what I wanted, I knew what I needed and I knew how much money I had. neither configruration was fitting with the money part and I bought used with low miles.
You might pull what you want with it- but here I ask the question- how long until it breaks down?
I think you somewhat underestimate what a load of this size does to your vehicle over time.
And the reason, why nobody answers who has a V6 and experience with so much weight is, because nobody even considers it and never done it.
As I bought my 4.7 I was also thinking about fuel mileage, maintenance cost etc... - and now after 3 years I had it, I had to admit- this engine is too small to pull this much weight. the good part- a 4.7 can be sold. for a V6 you have to wait for somebody who really wants to have it. so, if you buy it, you might stuck with it.
That's the last thing I say to this topic:
weather you buy the V6 Dodge or the 2.7L ecoboost - I promise - even if you would never admit it- you will regret it.
At the end it's your money- and the guy who pays, is the guy who says.
If you don't believe people who pull for years camping trailers around, nobody can help you. do what ever you want to do and be happy with it.
