The four indicated, and two at the back, inside the ramps, a couple on the tongue, if no winch or toolbox (I HIGHLY recommend a winch, I made do with a 2500lb, got a nine ton now), and two on the middle on each side, to tie down something other than a car.
I did see one wood deck with the d-rings bolted tonight. I don't recommend that......
Winches on a car trailer sure are nice, aren't they? I used to travel a little with a good friend (RIP) that enjoyed just going and getting the occasional car to clean and flip. Man that winch made it easy.
