I have a header transport that will do what you want. It is patterened after a Mauer and has two axles in back and the two dolly wheels in front. We made it in our shop. You can pull it 70 mph down the interstate and not worry about anything. Put new heavy duty tires and wheels on it as well as lights. Post back here if you are interested.
gben, We are trying to get lined up with a header trailer to move 30-36' draper headers. We travel long distances at high speeds. Does your trailer have surge or electric brakesIJ You said you put on heavy duty tires. What size are theyIJ
