My F150 is a 2010 model. Not a huge change from the current model, but I do have the last of the 5.4L V8s.
I bought mine new, but had all the goodies I wanted. The max tow package included a hitch, flat and round trailer plug, relay with heavy wire to charge the trailer's battery while towing, backup camera system, transmission cooler, an integrated brake controller WITH built-in sway control (see video), much larger - extendable towing mirrors, longer rear springs for better load handling, and a tighter turn ratio steering system. Quite a few things.
Ford integrated sway control system.The 1/2 ton term doesn't mean anything anymore. Mine is called a 1/2 ton, yet has a 11,100 lb towing capacity, and a 1810 lb payload capacity. The hitch has a 5000 lb tongue capacity when using a W/D hitch.
If you're considering a Dodge, please do some research on them, and read reports on how they perform with coil springs while towing. If you want a truck, buy one with a truck suspension. A close friend learned this le$$on the hard way.
I paid $8K below sticker price. I went to Edmund's website, built the truck of my dreams, then selected a number of dealerships to contact me with what they had, and their "internet price". This assumes the buyer is savvy enough to have done their homework, and know what the truck is really worth. No haggle price. It was a good deal for me, and still love my truck 6 years later.
Good luck on your purchase!
