Very Happy Titan Owner
 I purchased my Titan with the tow package to tow a travel trailer and serve as my main vehicle. The gas mileage around town could be better but it is still fun to drive. I am half way through my second cross country tour towing a 17' travel trailer. Mileage towing 14-15.5 MPG. In the Rocky Mountains I pass RVs and trucks all the time. Not one problem to date.
