Securing an E36 in an enclosed trailer, advice suggestions

I an getting a 22-24 foot enclosed trailer for my track E36.



I am looking for solutions to exiting car in trailer, or rely on winch for loading?



I am also looking for solutions to securing the car. Trailer has 4 D rings, but I can add anything that will make life easier and the car more secure. I have no experience with enclosed trailers. I have used an open trailer and know how to secure the car there. However, the limited access to the sides of the car when it is in the trailer concern me. Can I use the front and rear tow hooks as attachment point for straps?



I'm looking for E36 specific suggestions if possible. Bolt on tow hooks on both sides of the bumpers, tow points, etc. The slots for the factory hold downs aren't accessible with the car in the trailer and they don't allow for straps to go forward to the existing tow hooks. I've got about 5" of ground clearance so I can't run the straps that go around the wheels to the forward existing D rings.



I'm thinking of mounting more D rings outside the wheel width of the car so I could use wheel straps without running into the body/wheelwells of the car.



Thanks in advance!
