Acadia
Hey I have a 2011 Acadia, it is just Front wheel drive, it has the towing package which rates it at about 5000 pd of trailer.
Have only really used it to tow once. 2 place side load atv trailer with 2 full size atvs, both 600 pds at least. Towed from Idaho Falls up to Swan Valley with a good share of that with a pretty good grade. Yes the vehicle shifts the 6 speed tranny quite a bit, but round trip it got 14 mpg and coming out of Swan Valley there is Conant valley hill and it maintained 65 in 4th gear.
I actually was quite impressed, is it my main towing vehicle NO.
It handled the weight very well. Don't like the way you can here the ball in the hitch when it moves some, All in all it did pretty good.
Thats my experience.
