TMCNo1, thanks for the links - lots of good info there. What height / length (fore to aft) did you go with?
HS0skeefreek, same thing, do you know the dimensions / height of yours? Definitely looks like it would provide a lot of shade, I think I'd go with that length or 1' shorter iot keep a shady area over the passengers legs. Where did you buy yours, or did you have it made? Can the rear portion be made to sit level?
