I started using my favourite 2D CAD package before I discovered Sketchup. Since then I have had great fun designing the interior layout in 3D. Here is the final design subject to final dimensions once the van arrives, which at the time of writing should be soon as it is at UK docks awaiting distribution to the dealer.
So here is the planned layout of our van – subject to final dimensions once I get my hands on it. The driver and passenger seats swivel and the bench seat pulls out to a 1900×1200 double bed. The kitchen has a microwave under the hob and there is a 150ltr fridge with a big freezer compartment in the tall unit. At the back is a toilet / shower and behind and beside that is a bit of garage space accessed from the rear doors. You will notice too that Fred gets his own kennel.
Update : since I originally posted this and before work started in January the layout evolved a wee bit. The toilet moved to the left rear corner freeing up the garage space. The dogs kennel relocated to the bottom of the garage. The result is more and better storage with the only downside being 5hat I have to make a custom shower tray to cover rage wheel arch.
