Hi, Can anyone help? We have a Fleetwood Colchester with an awning size of 935. We have seen a full awning we like but the measurements are 910-934 or 935-959.We have asked at a store for their advice but they would not help incase we made them liable for giving wrong info. We usually pitch on level surfaces. Has anyone had this problem or can help give us an idea of which size would be the best to go for? Thanks Jenny
