Sunroof insert is not included so you can open up your freedom top panels without having to tilt the rack back. I have the insert with Rotopaks mounted on it, but I rarely use it...only on long trips. I like the idea of solar panels up there, but I mounted my solar panel on my trailer since that is where my auxiliary batteries are. I used a TV swing arm mount so I can follow the sun and also invert the panel when driving off road to protect it from mud and flying rocks/debris.
