My 10k gvwr 20' car hauler has 16" on center cross members with wood decking so I can bolt down through wood into the cross members. I use bolt on D rings with grade #8 hex cap screws every 4' for straps or chains. When I haul my 7600 lb blue tractor I use chains down under the outside main frame rails. d rings
I drill the square carriage bolt holes out with a 1/2" four flute core drill for those grade 8 bolts.
Some car hauler mfg will custom fab you a trailer with tie downs of your choice or they may have optional tie downs to fit your needs. Its costly but when you make a living with them its worth the cost.
Thanks a bunch JIMNLIN......that helps a great deal!!!!
