Oh, one other thing to keep in mind in case you are thinking of going BIG, there is limited power available. If you are in a 50amp RV, you will have a 30 amp and a couple of 15 amp sockets available. If you're in a 30 amp RV, reverse that. It sounds like a lot of power, but I know some folks with big displays who dance right up to (and occasionally over) the limit. Inflatables and LED lights use relatively little power, but strings of incancesdents (especially big C9s) can really add up quickly.
