No the tub is not original. Don't believe anything other then the VIN plate is still there. Pretty much the same as the Icon from TLC in CA. I know TLC has a way of having DMV okay the frame change. Believe the early Icons had the original frame. When I was over there in 08 they were already making their own frames. They still require the VIN plate(s), title and frame from the old cruiser to be 100% sure someone else doesn't buy a repo VIN plate and build another cruiser using the original frame. Last thing they want is another cruiser out there with the same VIN. Believe part of the reason for new frame is they claim the old one is damaged beyond repair. Won't be good to have the original frame still in use. How they got a title on this suppose FJ25 may be along the same lines except believe this was all done out of the country. Personally don't see a issue here in AZ. Years ago a visual inspection was required of vehicle coming in from other states. In 2008 when I titled my mom's Highlander coming from Nevada a inspection was required. Last year when I bought my 99 4Runner from a military family it had Oregon plates. When I got in line for the inspection after waiting for fifteen minutes for someone to show up at the desk inside I was told it wasn't needed. Only emissions if I was registering in a part of the state requiring emissions. If it has a title from another state won't be a problem unless emission required. That might create some problems, biggest being it's diesel. Probably why they used a FJ25 title for the conversion.
