We also purchased a Vango 'Tolga' awning in the summer after much deliberation. It is the baby brother of the Magra and was beset with problems also. It was a £600 purchase, looked great but wasn't fit for purpose! The water pooled on the roof as the materials were 'baggy' and the Diamond clear windows were so badly crinkled and creased you could not see out of the thing! CVB advised a hairdryer on the windows to warm them up to allow the creases to drop out but thats not gonna work when camping IMHO. It was up for 5 days in the garden, pooled water and remained creased all that time in a variety of summer weather... Not good! TBF CVB did accept it back as faulty and refunded. But a waste of time and research...
we are now awning-less again, and better off for it.
