Drop Floor

Or maybe raisable floor
I planning a drop floor in the back of a trailer but if I do it'll tear off going out of my drive way or up any other steep hill So my thought is a retracable drop floor that I can raise for travel then lower when I get to point B. Any ideas on an easy way I might accomplish this I've been racking my brains, it'll be about 3' x 6' by the way so it's a larger area to raise and lower.
Thanks for any ideas
