On our cross country trip last June, on more than one occasion or pure luck ?
When we parked in the campsites, the awning somewhat kept the afternoon sun from beating down on the side of the MH. Maybe not alot ? but it helped keep the MH cooler inside.
And it was nice too when it rained to be able to walk up under the awning and shake the water off the umbrella/jackets, then head on inside..
