We just got a new window installed in our AT Overland Habitat and we love it! The European designed window that AT is offering for the Habitat are double pane acrylic with a light tint — great views. Both a thermal privacy screen and a bug screen are built into the window frame and work separately or together. The window has an elegant look and design that uses a multi-stop window opening support vs the standard shock window support that only allow fully open or closed. These can be opened just a 1/2” and locked or they can be opened at 3 other levels. The window hinges do not open all the way, but you can still reach in through them. Plus one of the many very nice attributes to the design is that they do not allow the rain to run into the shell when the window is opened. It is a major problem when you open the typical hatch window on a camper shell in a heavy rain, because all the water runs straight into the shell. These windows do not have that problem. They will keep you dry in all weather and enable wonderful viewing; a picture window to enjoy nature when the weather is windy or wet outside your shell.
