This is what you need. It's rated at 10,000 lbs and is full 8 ft wide. It is on 15 in 6 bolt wheels and the fenders are about 3 in above the deck and are heavy enough to drive over. (I've hauled lots of tractors with the rear wheels sitting on the fenders) I run 8 ply tires and have hauled lots of 10,000 lb pay loads. This type of trailer is hard to find but there are a few out there.
