Hi ed325i,
I have been using the same NR Capricorn full awning on my van for the last 8 years.... it gets a lot of use, and so far has never let a drop of water in.
The awning was over 10 years old when I got it, so it has been in service now for coming up for 19 years...
NR awnings are very helpful in supplying things like replacement rubber suckers or the plastic pole extender locks.
I reckon they must be a top quality awning, if my experience is anything to go by.
Usual disclaimers etc
Happy Caravanning
