I went with the factory installed drop-in liner and am, overall, happy with the choice. It is a very sturdy hard plastic. The fit around the pro-power outlets is a bit tight, but the Ford roll-up tonneau cover I ordered thru the dealer fit perfectly on top of the drop-in liner. If you can't get the factory installed bed liner on the Pro, can't see any reason it wouldn't be a good choice for a post-delivery install by your dealer.
