We have a 2011 Chevy Traverse V6 and pull a hybrid weighing 3154 dry. It is rated to pull 5200.
Our Traverse does fine in flatter areas and in the smaller mountain canyons where hill grade is not too steep. Going up some of the bigger climbs here in Colorado like Vail Pass or the Eisenhower Tunnel it is a bit of a slow go, but manages it fine. I just keep it a bit slower than most of the other traffic as not to put too much stress on the TV.
The weight and drag of the trailer has the TV pulling around in 4th gear most of the time and sometimes 5th, but usually can't hold 5th for long.
I get 9-11 mpg towing.
We like our set up and works great for our family.
I think you will be fine just with the set up you propose, just be realistic that you and I are not towing with a truck.
I hope this helps, good luck and happy camping!

I pulled my Roo 19 with a 2011 Traverse for one season (dry 3383lbs, GVWR 4770lbs, but probably not actually over 4000 lbs). Just the DW and myself. I was NOT happy running in 4th all the time (~3100rpm at 60mph) on flat and level. Any little incline dropped it into 3rd. And I was just tooling around the mid-west, so I wasn't looking forward to any real hills. As mentioned above, it's not the weight, it's the drag. I'm on the Traverseforum.com and a lot folks there pull even more and don't seem to mind, but not me.
So I got a 2009 Silverado and I'm a LOT happier.
