Hutchbuggy 2 step by step concept

I never really finished my first hutchbuggy - it was my first vehicle in Rigs of Rods and I didn't entirely understand the process, but I'm back with the intention of making V2. At the moment I'm exploring potential designs, I want something that looks solid and mean, something you can rip across the dunes or roar around the back trails with. A meaty 4x4 buggy/truck/hybrid. Below is the journey of one of these concepts from a rough 20 second sketch through to the finished concept after about 30 minutes or so. Of course at this stage I'm really only interested in shape and design.
