We have steered away from the 270 simply because it’s for our bus and I am not sure how to even make that work. I will look into your suggestions though. If it were going on our Toyota it would be a 270.I would really recommend a 270deg awning. I have the 23Zero Peregrine with walls and the space is amazing.
Previously I had the Darche 270deg and it was nice but the folks at 23Zero fixed all the design issues and made one much better.
If you really need just a side awning the 180 series is a good option, you get more shade and coverage than a standard awning. Oh and I had a Hannibal for years so I am coming from experience.
