About $10k which is fairly considerable.
A Supercrew STX FX4 Ranger like how I want is $37k, a comparable Supercrew XL FX4 (with some dress up stuff, I don't care for anything that comes with the F-150's STX package) 5.0 F-150 is about $47k.
That is sticker to sticker, rebates vary and the rebate wagon is getting to the Ranger now.
Everybody likes to rub the Ranger's nose in it that the F-150 is cheaper with rebates... new models don't get them and the cost goes down the longer the model is out too. When the F-150 first went aluminum a comparable F-250 was about $5k little cheaper sticker to sticker. Now that the F-250 went aluminum and has been out awhile, it stabilized back so the '250 costs a little more.
Or they see a $45k Lariat Ranger and marvel that they could get an F-150 for the same price. And you can... but it won't have leather seats and LED headlights etc. The $48k XL F-150 I just built has halogen headlights, cloth seats and a rubber floor.
