hi,
bear in mind manufacturers size there awnings differently,so its sometimes better to pick the awning /manufacturer that will fit your caravan better.
bradcot are similar to isabell that the measurement they give is the central measurement (-----1050-----)
dorema size there awnings different ie 1050 is........ 1050-------1075,therefore would recommend if dorema to buy the 1050 1075,the 1025--1050 would be to small
it annoys me that some manufactures state a size but dont explain fully ,that that size, unlike dorema and others, that it is the central size...isabella bradcot take note.people see a size like isabella 1050 and assume its a size 1050-1075,its actually a size app 1038-1062 with 1050 been the central figure,no wonder people are baffled.come on you manufactures starte the exact measurements of your awnings and how they are sized and people might be more inclined to purchase your products.
