It's a interesting idea. I would mount a covered switch through the side of the bucket instead of using a plug to make and break connection. I would also use a GFCI outlet to protect the circuit. The design is perfect for a display booth at a convention or for lost weekend in a industrial loft, but I would not use it camping. For me camping is outdoors and in the dirt. Chair casters don't do well on uneven surfaces and soft ground. Buckets tend to collect condensation and that doesn't mix well with live wires. You should be aware of a potential safety issue. Power run through a coil of wire creates a magnetic field. If there is no ferrous metal for magnetic field to act upon it becomes a air core inductor and the wires create heat. To be on the safe side undo the entire coil before running power. Nothing worse than a bucket meltdown.
