Find a different dealer. I may be a little spoiled by my small town dealer where I bought mine. They are not biggest or the busiest but when I took my 17 in for a strange noise coming from behind the dash I called them and they told me to bring it right in and they gave me a 2018 XLT Screw as a loaner which I ended up having for three weeks. They had a full tank of gas in it and told me not to worry about it having a full tank when I was done with it. When I went to pick my truck up today they washed it by hand and even cleaned up the interior.
I could have saved a few bucks by going to a big city dealer but in the long run I would rather spend a little more up front knowing I will be taken care of by my dealership in the long run.
