Just purchased the latest Trigano Luna 280. What is mentioned in the user guide is not reflected in the sales blurb. If one of the arches is damaged or punctured, it cannot be repaired and has to be replaced, and it is suggested that you carry a spare. I was disappointed when I read this. When viewing the awning, we saw little padlocks on the zippers and wrongly assumed they were a security feature to stop theft of parts. I only found out when I asked for a key and was told the manufacturer, did not want you to open, but the instructions state they are there to help with inflation. As the awning only pumps up to 5 PSI, I can't see why punctures cannot be repaired. I suspect this is a ploy to get you to purchase expensive spares, which kind of spoils the lightweight awning.
