Cvana at Tauranga do more than fit awnings to vans and caravans. They fit enclosures for the fitted awning as well but more relevant is their service and repair capability.
I needed 6 zips repairing and two rips fixing on my caravan awning. They said they could do that, they said when they could do it. They did it in less time, to better quality than the original (not theirs) at below budget. They even identified a further fault and repaired that within the job. Brilliant, cheerful helpful service from the team at Tauranga.
