Totally confused myself. We are looking at awnings at the minute. Just want a cheap second hand metal piled type to go on the side of our Ducati 6.4m PVC. We don’t have a Dianna or similar onto which to fix it but have an awning rail attached to the side of our van at 2.35m from the ground. Can anyone please advise. Do we need the high or low versions. I have been looking at one which shows it attached to a PVC but then says maxes attachment height 1.85m. See why I need help. Thanks
