The front section is 4x7 the width at the back gate is 5 wide and the full length of the inside trailer is 12 ft. Tires are in very good condition. The lights do not work and would need to be replaced. 2 inch 64 Shasta coupling locks up tight and the jack works great. The trailer tag is missing I can not find it, it full size six lug tires, should make it 5200 lb, Heavy duty solid trailer.
