We put a maxx air deluxe in our trailer. I was pretty nervous starting out but it seemed easy enough so away I went. It was pretty easy works great has a remote control. There is most likely a power wire nearby to tap into. If there is a light near the opening then you have a power supply just plan on where your wires are ging to be put away before you cut them I just about cut too far away fom where the wires fom the fan would be hidden. There is video in this link for the install.
