Because my brother and I are getting one for our dad?
He's retiring and told my mom he wants "a little red truck." He wants a Ranger to beat around, but we're likely going with Red Fire with dark charcoal interior.
As for towing capacity, I've pulled nearly 4,000 pounds with the SOHC V6. Properly equipped, there's no reason the V8 cannot pull a 4,500 pound boat. The engine is spec'ed at 6,900 for 4.2 and 7,100 for 4x2.
Edit: Tom's onto something, though. The price of a fully loaded ST is the same as an '07 150 FX4 with luxury package, navigation, etc. It's likely you get "more truck" for less money with the F-150. Hmm
Edit 2: More credence to Tom. (Don't get full of yourself.
) The F-150, if paying monthly, offers 0% at 60 months; the Trac is at 36 months. You can't go wrong with 0%--you're buying with Ford's money, especially when considering your funds earn interest during that time. The interest you earn over the life of the vehicle decreases its overall cost...
