I just like a truck. But am also thinking about a car for this purpose as well. Don't laugh, but I rented a Toyota Prius one time when I was traveling and really liked this car. Everyone I know who has one says they are 100% reliable on top of the incredible gas mileage. With gas prices coming down, this might be a good time to get a good deal on one. I won't let my wife buy another SUV (ours is starting to get old) until she test drives a Prius.
I wish they had a diesel version!
One of the best trucks I've ever owned was my 93 Dakota sport with the 2. 5 4cyl and a 5-speed. It got about 30mpg on the hwy and had plenty of power. I once towed a 74 Chevelle station wagon about 25 miles with it. It pulled it fine but was a little touchy to stop with no brake controller. The cab was roomy and comfortable and it rode and handled quite well. Before you mock the 4cyl it had the same peak hp and torque of the 350 v8 in the wagon.
As for the Ram 50's, I own a 87 that I need to get running again. These were good little trucks. Torquey but not a lot of hp especially at hwy speeds. The biggest drawback is the feedback carb that is almost impossible to get worked on anymore. Mine is a longbox 4wd with the 2. 6 and a stick and it got 21-25 on the hwy. Right now it needs a carb and an intake swap. I really want to find a small diesel to try a repower on it.
