The days of the compact pickup are fast closing. Witness the 2009 Nissan Frontier, a once-compact contender that has grown in size, power and weight. Along the way, it has also grown in capability and passenger comfort, placing it in the same general category as the mid-size Dodge Dakota and Toyota Tacoma. The Frontier has much in common with its larger sibling, the Titan, offering a fully-boxed frame, Nissan's adjustable Utili-track Bed Channel System and a spray-in bed liner. With one of the most powerful V6 engines in its class, the Frontier offers superior towing with excellent acceleration. Although bargain shoppers may lament the absence of a standard-cab model, the four-cylinder King Cab is still an affordable truck, priced under $20,000.
