A: Snugged down tight it would stand up to short trips. Material is very strong, we had 4' of snow on our boat this year then it turned to ice, no tears or unusual wear due to the extra weight from the snow and ice. I was surprised and impressed with it's durability and fit. 
A:  The rear support poles must be disconnected to fold the top down. the sockets on the top support bow are fixed position. the connecters provided are screw type ,I replaced mine with pin clips for an easier and quicker set up and take down. if you fold the top to the back'it's flat,if you fold to the front, the curved shape of the front bow keeps it from being flat.
