It's a shame that the auto makers have been slow to introduce turbo-diesel engines into the USA, although the reasons are pretty obvious. Gasoline is a lot cheaper than diesel (in my home town right now, gasoline is $2 per US gallon and diesel is around $2.60) and diesel engines are also more expensive.

IMHO, the power and especially torque curves of the typical turbo diesel are absolutely superb for towing. I am now towing with a camper van based on the Mercedes Sprinter and find its towing and hill-climbing abilities to be superb. Fuel consumption is also not far shy of 20 mpg (that's 24 mpg for the Brits!) My other tow vehicle (Lexus with 5 liter gasoline V-8) is also superb, but it's a lot bigger, heavier and thirstier than most would like to drive around, especially in Europe.
