We have Carefree trucking awning. Its sole purpose was getting in out of camper when raining, shade to have door open etc.

Does offer some shade to back of camper but as it only extends 4'(autorafter) not so much a shade awning to lounge under. Yes there a better shade awning options, also more expensive- depends on its intended use.

Ours is 9 1/2 years old. Fairly straight forward install.

Maximizing size hardest part.
The standard has 36" projection -the auto rafter 48". The 48" keeps the rain and sun outside when door open.
