I did a bit of work on Monster's one and some of your mods are first rate, I love the rear hatch for starters

- I can't see any issues with your proposed camera vs. rear visibility thing. It would certainly kill several birds with one stone but you may need to check for mounting and vibrations as the rear end will obviously be shaking around a great deal.......not sure about how forgiving the camera is. (Not a criticism of the idea by the way)
- I am surprised that you're ditching the intercoolers and oil cooler for the brands you mention. If you swapped the twin coolers for a big single, I could understand. I do love the ARC's of this World but I never found any gains in performance over the British brands.
I'd be really interested to see the weight that this comes in at. Keep us posted mate.
