Thanks for asking for our input. This is a great topic - we've covered some of these before (like in the "what would you tell Ford" thread, etc.). My input:
* Skid plates - the truck is essentially unprotected from below. I don't think we need full underside protection but there are certainly some areas that need protection and I suggest you prioritize them and offer skid plates for those areas that can be added as owners' budgets and priorities allow.
* Front skid plate - BigJ hit the nail on the head - why spend money on a replacement from Ford that is no better than the one that came with the vehicle?
* Rear diff protection - Something that actually works. There are many designs out there (

* Removable bed rack - There are two options here (at least) - one would go inside the bed and could hold spare tires and gas cans, etc. The one I'd like to see is one that goes over a bed cover that mounts through the bed rails (through the plastic covers or, better yet, inside the bed and wraps around so it's mounted inside while allowing a bed cover to be used). I'd like to be able to mount a spare tire or two flat on a tubular removable rack that's just above my bed cover (BakFlip). You also could select a high quality gas can (plastic or metal) that is CARB (California) compliant and make a gas can rack that goes in the bed (perhaps just behind the cab on the floor).
* Swing-away Spare Tire/Gas Cans/Hi-Lift Jack rack - Not like the "tire gate" product, this one would allow the tailgate to be used (and even allow the camera to see out if that's possible) while mounting a spare tire, gas can and a Hi-Lift jack. These things are made for Jeeps (see pic below) and given the width of the Raptor there's more design flexibility.
* Removable roof rack - Something that doesn't require drilling. (This may already be available for the F-150 from rack makers).
* Rack for behind the cab - Could be used for mounting lights over top of the cab as well as to the sides and back. Also could mount up a Hi-Lift Jack, etc. This could also be integrated with the on-the-floor gas can rack I mentioned above.
