Hey even the evil Empire likes to have a barbecue now and then and when they do they do it in style. R2 has caused them quite a bit of trouble over the years and now it is payback time. The droid will be made to serve the empire by cooking up some delicious meat.
If you have a 55-gallon drum lying around and Smoker, you can create one just like this. Then give it a paint makeover. May the force and good burgers be with you.
