No, our unit was supposed to have the generator prep - at least that's what the dealer said. We didn't order the unit though, we bought it off of the lot. When we found out it didn't have it, my husband contacted Scott. He did some research and discovered that yes, the build sheet listed it, the dealer was charged and so were we. We do not know what the cost is. Scott sent us the kit (minus the metal enclosure box) to make things right. The box is just to big to ship.
