Facinating! I love this idea. Now when I look at the European market, I see a LOT of different styles by various manufactures. I should think that it could be very easy to get someone else to build this thing for you, and for not much more than your estimated build costs. On top of that if you are pondering shipping to the USA, you could ship the truck as it sits over to the EU state of choice, and have them install it. Then just go pick the thing up in person. Saves the shipping costs, and sort of gets you to Europe all in one.
I would be interested to know if you looked at Yves' build, (westyss), to see what he has going on in his. The FG would seem like a possible option for you, and I know you already picked up a vehicle, but I would like to inquire as to why you ruled that vehicle out?
I will whole heartedly sustain your choice of the ARB locker on your vehicle. I think that is a great help, and in my experience the ARB is a wonderful choice, well worth the price. I think a slight lift, of say two inches, would not go amiss for you as well. Just a touch bigger space, and some slightly larger tires, I believe, you will find will give you a tremendous advantage.
It will be a shame to have to leave your motorcycle behind, but such is life. At least you will be less likely to require a vehicle that can scout ahead than you might currently need in the W2.
Oh, yes, I almost neglected to ask... Why did you not choose to go with glass? I do not know much about the weight characteristics of fiberglass, but it seems like a very easy medium to work in, and furthermore it also would appear to be a fairly budget friendly material.
Well I look forward to the day that you complete your vast research efforts, and show us some photos of your highly anticipated build.
