George Neville Easy Sheet

After having had quite a few George Neville easy sheet’s on 8 wheel tippers why are not more seen on bulk trailers ?
I found them to be a far superior product to Dawbarn. The only down side to them is the opening and closing can be slow meaning you had to be careful in high winds.
The Dawbarn product looks worn out after 6 months and know people who have had a lot of trouble with the Wraptors.
Has any body tried the new Wraptor 2 that seals on the top rail and is it still fixed to the opposite side rave or on bungy’s ?
