    i have a a low pro stepdeck,when i load a heavy item on a small area(coil,machinery)the trailer leans to the left.the frame looks ok no cracks or anything.this doesnt happen when the load is spread over the deck.the only thing i noticed is that the air bags on the left side dont go as high as the ones on the right side and the metal support under the bags is slightly higher on the left side.anybody have any idea of whats the problem?thank you in advance.

    You must be sure coil is in center of trailer,A larger coil may have bent it, when empty run a string down both sides of rubrail 1/8 in away from side rail,if bent you will learn how to load it off center to make it look good going down hiway.

    Check that the metal holder is not bent or damaged. There are some styles of air bags that are plastic with brass threaded inserts that couple them to the holder. These are NFG IMO because the bag mount does not add to the strength of the mounting holder and help prevent it from twisting/deflecting. The plastic style bag mount will crack and the threaded inserts will not hold. You can find better bags with a metal mounting system.
