What's a reasonable approach/breakover angle for a car hauler?

I'm thinking 30 degrees from the ground to the tailgate (which would also make a 30 from tailgate to trailer...)

Pythagrom therom then states that for a 30 degree angle from the ground, the tailgate would need to be 2x long as the height of the trailer.


Does this sound reasonable?
Main vehicle on this would be trucks/rock crawler/Jeep. but I could see an occasional 4dr sedan going on here too.

Thoughts? Suggestions

Please go back to math and engrish classes. When you have learned what it is you actually seek, then come talk to us. Approach/breakover angle of a trailer is a moot point when it's a carhauler.

What it appears you want to know is how long to build your tailgate. Get the trailer done first, then figure it out. Since you have no info on the height of the rear trailer deck, you really can't figure it out.

You building it to haul your rig, or to haul other people's vehicles? I just cut my ramp down, make it nice to have a reason to give why I can't go pick up someone's car. If I absolutely need to I can use extensions, but otherwise I don't have to feel obligated to haul a car for someone for nothin', yet it's still cake for my Jeep to get up.

Pythagrom therom then states that for a 30 degree angle from the ground, the tailgate would need to be 2x long as the height of the trailer.

The Pythagorean Theory has nothing to do with the 30 degree angle. It works on any triangle that has a 90 degree angle. It also isn't 2x as long as the height. It says that the height squared (squared is not 2x) plus the length squared will equal the square of the distance from the beginning of the ramp to the top measurement of the height.

If that isn't clear enough I suggest a basic angle search on google.
