Go with the one with the Tonneau. When buying used, just check for leaks under the engine, or spots on the ground, look for burns in the upholstery, and pull the fluid sticks (tranny, oil) and see if the oil smells burnt. Usually the owners of dakotas take care of them. They are great trucks. When you drive them right, they will give you good gas mileage. Even my R/T doesnt do that bad. The main reason they dont get good mileage is because they are strapped down so bad from the factory, with all the oxygen crap on them.
