I created a very detailed model of an RV and a sway control hitch (you can find the hitch in the 3D Warehouse). Figured I'd do a nice render.
The grass was created with Skatter.
I used a 4K environment map (HDRI Haven has some great free HDRI maps), which gave some beautifully realistic reflections and shadows. Texture Haven provided the concrete texture.
I didn't create the SUV; that's a Nissan Pathfinder model from the 3D Warehouse. I did, however, tweak the brake lights to be transparent, which looked a lot more realistic.
