Access to a main power source within fifty feet of the front of the trailer location consisting of one 20-amp, 110 volt dedicated electrical outlet. Failure to provide the electrical requirements may damage the air-conditioning and heating unit. If it is determined that the electrical supply is inadequate, the electrical box controlling the air-conditioning and heating units will be padlocked and the air-conditioner and heater will not be available for usage. For an additional fee, A Royal Flush can provide whisper quiet generators to provide power for the trailers and a water source if these items are not available on site.
