I went with the SCAB for a lot of the reasons you listed. I didn't need the extra room, the lower tow rating isn't an issue, the smaller tank isn't an issue, I still get over 400 miles to a tank, easier to park, shorter overall length helps with break over, I personally think its looks better, and more unique because just about all of the Raptors I see are SCREWS. I will agree with what some have said you are likely to have a better resale with a SCREW, the bigger gas tanks means less stops at the gas station, and the higher tow rating could be useful for some. If resale, bigger gas tank and the better tow rating is important for you, go with the SCREW. If I had to do it over again I would still get the SCAB, only I would of paid the extra for the tailgate assist. When I ordered mine I forgot to add that.
