We have an older Carefree manual awning (Freedom III) and I have been totally pleased with it. It is now 13 years old, and still operates perfectly (knock wood). I do not strap it for travel - its aluminum clamshell has always done the job of containing it well.
Note however that it's a side-mounted awning, not a roof mount. I don't know if this kind of model could be used on an NCV3.
Gear failures in older Carefree awnings are reported, but we have a DIY parts replacement guide from an Interstate owner who took the trouble to photograph and PDF the whole procedure, which is fairly easy. This pushes it closer toward the "bulletproof" category, as van gear goes.
Here are the features of the Freedom III that I like best:
(1) Those support legs that anchor it to the van. Extra security. No way for the thing to flip up over the roof in a sudden gust.
(2) I can manually extend it out a short distance, so that if there is light wind, I can still use it, just partially extended. In fact, I almost never extend it fully, and on those rare occasions when I do, I never leave it unattended.
(3) I can manually jack up one support leg higher than the other, tilt the awning and allow rain water to drain off it quickly. The manufacturer does not warranty it for use in the rain, but with LIGHT rain and PARTIAL extension and ONE leg jacked up for drainage, I have used it this way without damage or other issue.
(4) The manual awning general arrangement allows for the use of a bug screen the way that a legless retracting awning cannot.
