I am shopping for a basic open trailer for a 2nd gen. RX-7. Is there any standard for the amount of dove tail droop? I looked at some today and the wood decks had mitered side rails w/ a good 3" drop over the 2' dove tail, but the metal decked ones were not mitered and had anywhere from 1.5 - 2.5." I'm thinking I need all the droop I can get since I'd rather not have to jack it up in front to get a good angle. Any experiences w/ this?
