What's the longest/heaviest you would tow with a 1/2 ton?

I'm going to drive a new Ram Warlock the weekend after next. I'm probably between it and the Titan just due to pricing, but we were very impressed with the Titan and were shocked by just how much. I can say the interior fit and finish and quality were far better than the Chevys, Fords, and Rams I've been in. Asian built vehicles tend to have a better reliability record. I've been a new car dealer service advisor for 22 years and have seen a lot.
