Very quick little project:
Rendertimes are about 25 mins for a 1280x720 resolution.
Nothing special in the setup.
I particularly liked how the 2-sided material worked out on the trailer roof 
i like the 2 sided as well. Don’t use it much though for render times. 
Render times are long if you use a vraylight behind them. However, I found that using a plane with the vraylight material applied instead of a vraylight will cut the long render times significantly while achieving the same look.
Nice render, sorry to go off topic.
