A 322 weighs at least 10,250# dry, no gear, no extras, just the boat as she came out of the factory. Add weight of the trailer and normal sailing gear and you are well into the realm of a "Big Rig" or at least heavy-duty pick-up truck. Plus, not many ramps are really designed to easily launch/haul a sailboat drawing 4'2" off a standard trailer (Hydraulic boat-hauler trailer...... sure, made for that type of ramps) and even if you COULD find a suitable ramp, stepping/unstepping the mast will require a crane or else some fancy modifications.
Yes, I suppose you could, with the right setup, become your own "boatyard" and haul a 322 out in the Fall, store her at home, then launch in the Spring...... but it will be a big job!
