I have a 16ft tandem axle trailer with removable ramps. Probably a 5000#GVWR. I haul my tractor and small cars on it. It has a rail around the bed.
The trailer brakes don't work. Don't know how many timbers you will be hauling, but you may have a problem with the Nissian stopping the loaded trailer.
You can use it if you need to. I'm in N. Ala.
