The fun of not knowing where to start! It's very dificult to make plans of any use without the truck. Personally I'd be getting your truck home, and then once you have it, you'll know how it drives/handles etc. You can then look to Hab Box design to suit your truck, and then play with engine power requirements, wheels etc later. I look back at my truck when I bought it, and how it is now and it's quite different... Different wheels, cab lifted (using genuine parts from a later truck), 40mm front axle spacer etc etc. Air tanks have moved on the chassis, as have the batteries. All to suit the layout and look I want to acheve. I have also retained the duals on the rear (which is a thread in it's own right) as I want tyres that are easily found, and like the idea of having 4 tyres holding the truck up at the rear in the event of a puncture. You have a lot to think about. If you decide to go with super singles out of Europe, you can at a later date once you know exactly what you want. You could just ship the rims you require over and then source tyres locally... I only made truck mods once the hab box was sat on the truck for the first time. The few things I bought/sourced early in our build have long gone. They were sold as they were not suited to the truck, or just didn't fit in the space available. Just my thoughts though! Enjoy the excitment of shipping, and hard though it will be, my advice is to sit on your hands until the truck is in your yard!
