When I purchased my present TT my TV was the same truck you have only a 1999 with less horse power and tow package. My TT weighs about 5000 pounds. My TV did ok. I towed in third gear with the tow/haul mode on. But my towing is Florida towing with small hills and mostly flat roads. I did have to use 2nd in some heavy head winds. I never towed above 63 mph. The truck is the same truck as the 5.3L version. Expect 6 to 7 mpg towing. Make sure you put LT tires on your TV. My TV was also 2wh drive. The 3.73 rear will help a lot.
