I have a 4 x 8 dump tailer made by Country Manufacturing. It's a simple trailer that is not for the road, just on the farm. It has dual tilting axles with 22 inch ATV tires. It has a 4000 pound capacity. I've had it for 10 years, I've moved hundreds of heaping loads of dirt, way more than 4000 pounds per load. It only cost about $1K at Northern Tool. If you need an off road utility trailer I'd recommend this one. The only problem I ever had is that the dump hinge is a little light duty and I had to replace the female half of the hinge with a heavier steel tube. Cost me 5 bucks and some welding time. No problems ever since.
