I'm pretty tall (6'9"), but those wings are up there when folded. I could probably lift my corner up that high, but I doubt most other people could.
When I triple stack I get around the height problem by lifting the front of the trailer as far as possible then bracing it in that position then it's easy for two people to put the top boat on
