hi everyone , i just bought a used tandem axle trailor rated for 6000 pounds . it has no bunks or rollers on it , i have decided to go with the bunks but i am going to make my brackets at work , out of heavier steel , the bunks are going to be 2x10 and 10 feet long covered with bunk carpet , my question is do the brackets go on the inside of the frame or the outside of the frame ? thankyou . the trailor is going to hold a 1989 thundercraft 220 magnum ..
