How about a full sized hybrid pick up that gets about 30mpg and doesn't give up much in the way of towing at that efficency? They've made them as prototypes- give it three or four years.

But I think the "horsepower" argument is the most pointless I've ever heard, unless you are just being belligerent. No one is saying that hybrids work for everyone- they don't. I wouldn't bother, because as much as I like them, I don't spend enough time in city traffic to justify it, for my type of driving you can get the same performance for less money. If you need the towing power, drive a beast. But if you can't justify the expense of owning such a truck, why would you want to?

A car is a tool. You buy the one that best fits your needs and budget. Anything else is just Freudian.
