Whatever floats your boat, go for it. It will bring lots of admiring smiles but only pennys on the dollar when the time comes to sell. That day WILL come. I like different too. I have a very rare 5er.
That lOA is going to severly limit CG site options never mind CG owners saying no to the noisy truck. An old rattly diesel is not music to everyones ears. It is sort of like restoring an old classic cruising boat. We sure do appreciate what went into it, the work & expense it takes to keep it, love the looks, but no thanks to owning it.
