Yes swing out tire carrier would be sweet.The rear bumper you made for the JL in the video is beautiful! I believe the styling is perfect! If it were my bumper you were building, I would want you to make the sides wrap further around towards the rear wheels for rock protection, incorporate a step, add a couple Hi-Lift points and have the sensor compatibility. You could also have a couple optional models with or without swing out tire carriers. Dual swing out or single swing options on a retrofit bumper? People love options! Lol! I truly believe your style is great and I wouldn't change that at all from the JL bumper. I would just add to an already great design. Thank you for your information and your time. I look forward to seeing what more you have to offer for the JT in the future.
