Is there a on line owners manual? I'm not interested in buying one, just want to read through it for interest.

If there is no such on line animal, does the original manual state a max speed for driving with the door(s) open? Do they try to close via aero-dynamics? What about hitting a bump? It would seem like the door could be damaged by hitting the up stop to hard. In fact, do you guys pop the door latch and just let the door go up by it self or do you control it on the way up?
