With the rig you are contemplating, it comes down to how often, how far, how fast, and in what terrain you want to tow the trailer. For occasional short (couple hour) trips at 55 or 60 mph in the flatlands, you should be fine. But if you want to go 70, or want to take long distance vacations, or plan to visit the mountains, you'll find the experience quite dissatisfying and you may burn up your transmission.
I tow a 16 foot travel trailer about 2700 lbs loaded, and for work a similar size cargo trailer up to 3500 lbs loaded, with a 270HP V6 2008 Toyota Highlander. I have used the Highlander to tow for over 125,000 miles (there's 158k on the odometer). I've gone through the Rocky Mountains on three trips. The Highlander has done the job pretty well. But I have to tell you, I would not want to tow anything bigger or heavier on these trips. And I am getting really weary of slow travel speeds and 'just enough' power, so I'm looking to replace the Highlander soon with a Jeep Grand Cherokee diesel. Put me in the "been there, done that, ready to move on" category.
