I know that James Baroud has thier own awings that work with their tents, even have a removable section with a tunnel to connect to the side entrance of the tent so you can exit directly under the dry awning, then you can attach walls to enclose the space. They come in both 270 and standard types. They are rather proud of them pricewise though. The ARB and its clones are probably the smallest and lightest awnings I have seen, but have limited protected area under them and take a bit of time to set up and stow away. Most of the 270 styles are fairly heavy and have substantial mounting requirments at thier hinging end, they typically have certain specifications for locations of the mounts also. The standard roll out side awnings have a lot more flexibibilty on the type of cross bars they can mount to and do not transfer much if any load to the vehicle when deployed.
