What do you pull your cars with?

I've got a wood-floor trailer (open in the middle) that weighs 800 pounds. My Duster weighs around 2800, and I tow those with my '97 Dodge Ram 4x4 5.9L. It's great on the highway, struggles a bit on big hills.

My neighbor used to tow a similar trailer with a Camaro on it - weighed around 3500 pounds - with a 2000 (I think) Dodge Dakota 2WD with the 6 cylinder. He had no problems with that, either.
