If he is planning on producing these there's a couple things I'd be concerned about.
- What if you don't have the winch bumper? Will it transition okay with a stock bumper?
- IMO the bumper should overlap the skid plate in the front.
- I'd definitely want some kind of ventilation on the back half. If he's gonna sell it in 2-3 pieces that would work so you could use the OEM UCP.
