You might be able to sell to Top Gear people but they would be more interested in setting it on fire then a holiday weekend on the beach.
Difficult to say but you're going to run into multiple problems, costs, input duties and such. The coach is set up for 120VAC 60 Hz which is going to be your first problem. Propane tank might not meet EU requirements, required road safety standards might also be a difficult problem. Demand sets price so is there a demand for coach of that size?
I would sell it here and not take it back to the EU.
