What truck is needed to tow TT weighing 10k lbs.

The V-10 is a great engine. Much better option than the Ford diesel of those years. It will tow 10k lbs. with no problem provided it is geared properly. My 02 V-10 toes my 9200lb loaded TT with no issues. I get 7.5 mpg avg. the 2010 should avg 8.5. Height is a bigger factor in towing performance than weight. My TT is 11.5ft tall. Some are 10.5 which makes a difference. Either way you need the specifics of the truck your looking at. Gear ratio being a big one at the weight your talking.
