think of it as an accordian bag. its very flexible so it will still allow the cab and bed to move independantly. but you must do it right, otherwise the first rain storm hits and you will be in a truck without a paddle..... although i wouldnt be offroading anymore with this type of setup.
And, you may be taking a huge hit on resale potential (and value) unless you can find someone who wants a Raptor that has that major liability in regard to off roading.
