When I've trailered my car I've been able to drive it on. The tires are biased towards the rear. I leave the window down so I can get out. Otherwise I would use a winch. I use those yellow ratchet stapes that are 2+". Go over the A frame and through the middle. Under the center and then back through the A-frame from below and over the top towards the tie down on the trailer. I also use tire chalks on front and back. I tie each tire together with a small rope so they don't bounce out. Here in my state it is "secure your load" and if you don't you are liable for the results. I've never had to use a ramp truck but I would go with Rocky on being there.
