My favourite topic.
I've had a kings awning for 4 years. Been all over australia and it's still sitting well on my roofracks. The awning itself is fine. Tie it down on windy days and it doesn't flap around too much. If it threatening to rain, just drop one corner to ensure the water drains off. I don't see the need to compete against the three letter brands to see who can make the biggest swimming pool on top of the awning.
Also have their light bars, battery isolator, scan gauge, 160W solar panel, 'chair bags' for the kids, LED camp light, 12v shower. All no issues.
Their stuff has improved our camping experience. We generally go somewhere every two-three weeks so everything is well used.
