The overall experience is OK but not great. This is the only car I have used to tow a trailer so can't do any compare. I had to leave the tranny in 4th gear all the time. It runs good on flat road and short slope. I haven't tried any serious mountain trip, will try it out next year. Gas/milage is terrible, I got about 10mpg roughly.
I have a V6 Toyota Tacoma, and get 11 or 12 mpg if I take it relatively easy (60-65 mph) on flat to rolling terrain. Mine's an automatic, but I often leave it in fourth gear, rather than drive, and don't use cruise control.
I'm towing our FF 160 with my 2004 Nissan Pathfinder. It has a 3.5L V6 and yes, it does seem to be a bit underpowered. Going up long grades I am slowing down to 50mph and straining. But most of the time cruising at 60 mph is just fine. Mileage is around 12 miles to the gallon. So far I've put around 3000 miles on the trailer (its a 2009). It is highly recommended to get a trans cooler. I also had my cooling system flushed and front brakes replaced. I never use overdrive (the truck has a switch to turn it off) and rarely use cruise control, except on long flat roads.
