is the 4 cylinder strong enough to tow?
depends on what you are towing. I mean, it could. Probably not the absolute best thing for it. Look into some bigger brakes and a differential re-gear. That will definitely get you started.
Don't listen to David. I have the 4cyl access cab 2007 and I tow a travel trailer hundreds of miles per year. It is 2k lbs and a total of 2,800 with gear and people. No issues.
