Step one complete. I bought a hydraulic tipping trailer with a complete flat bed. Very easy to operate and drive on to with no clearance problems. Pics to follow.
It has two axels so a potential blow out is not so scary considering the valuable cargo I have.
Next step to manufacture some wheel U sections with a solid front which will help securing of the car.
Then maybe a lightweight frame and tarpaulin cover.
Another bonus is I thing I can keep it in the garage with the car on top, maybe fix a towing hitch to the garage wall.
