I think cantilever is a really neat concept but I prefer this setup for a number of reasons. Most of all I think there needs to be a stopping point on these trucks in regard to mods, at a certain point it no longer makes sense to me to mod a raptor instead of building another cheaper vehicle for less. Long travel is cool and all but you pretty much need to back half the truck for the rear to keep up, at that point it no longer fills the role of the truck that I need nor does it make sense to me financially. The towing thing already mentioned is two. And three is the desire to be able to revert to stock for sale if ever desired. This rear setup is an absolute screamer of a performer and it's a nice compromise to me. All of this is just my opinion and I love the trucks that take it all the way and push the envelope, it just isn't for me, I want the most possible performance while retaining the most factory capabilities and resale value.
