I switched back in end of July from XL to XLT from what I heard I'm still a 22 but I'm at the end of the line now, Didn't know that when i made the switch, don't know about the price yet. My dealer is doing the reorder today. I ask for copy of the order and new pricing.Starting with your private offer. How ever much that same truck you originally ordered without changes later, that is how much you should get. Whatever that same XL goes up in a 23 is what you should get in your offer..........Secondly, Tim Bartz, Ford Video Guy, says even if you change engines, you should retain your place in line. I asked him this live on his You Tube Show about 6 weeks ago. I know that could be a huge choice to switch if that proves to be un-true, but that is what he said. I would try to confirm that with him. And yes, all this needs to be done at the same dealership as your original order.
