got no idea on these particular brands, but sometimes you get what you pay for. My Gunya awning costs twice what others cost many years ago, can't imagine people stumping up $800 for a normal awning these days when cheapo Supercentre seems to be the rage now....but 10 years later and on it's second vehicle now, my awning is still going strong other then the canvas being a touch faded and a few stains on it. I've witnessed 2 Kings awnings break from a bit of rain on them on the same camping weekend away due to their flimsy poles and light weight awning material, even though both awnings were on angles that should have let the water run off of them whilst roped down in position.
Your $800 buys at least 5 units from Supercentre. There'll be some annoyance but even with a few replacements down the track, cash wise that's still way in front.
