also if you tow anything, the supercrew has an 8,000 lb tow capacity. The scab is only 6,000 or 6,500.
My 2000 HD drag truck with trailer is about 6,500-7,000 lbs, and after having a second 2000 HD truck to tow the matching "race" truck, with only having a 5,000 lb towing capacity, I had enough with trying to tow out of the capacity of the truck. I went with the screw primarily for the added towing capacity. And it tows oh so nice!
Added bonus was the extra interior space. The new scabs are pretty roomy in the back, especially compared to my 00 HD scabs, but the new screws are MASSIVE! It has been really nice not having to worry at all about trying to cram passengers in the back. Load up 5 adults with ease, and nobody has to gripe about being stuck in the back, because it's roomier than the front lol. And when kids eventually come, it'll easily fit little brats, with plenty of room so they won't be able to reach to even kick the front seats till they're old enough to know better lol.
And the screws have a 36 gallon tank, the scab is only 25 or 26 gallons. With as thirsty as the 6.2 is, and I hate having to stop for gas all the time, I absolutely love the 36 gallon capacity. I always get ~500 miles to a tank. It'd only be ~360 to a tank with a scab. Yeah it's more money to fill it, but it's less often, in the long run it's no different, I just prefer stopping less frequently and having an extra ~150 mile range.
Lastly, resale value! Screws account for around 80% of the orders. Of course all raptors will hold their value more than an equivalent regular f150, but screws are 4x's more popular than scabs, so it will be easier to sell if you ever do decide to get a newer one, or get something else. Up to you whether you prefer the more rare one, or the one that is more in demand. Personally the Raptor itself is rare enough, I went for the one with more towing capacity, more interior space, more fuel capacity, and more consumer demand. Just a few other things to think about!
