The air suspension is easily adjusted for trailer load. The trailer wheels are designed to have six degrees of camber either way from vertical. To adjust the suspension simply look at the wheels. If they toe in or out release or add air until the wheels are vertical. When the wheels look right they are right.
Adjustment is easy to do each time the load is changed.
Gold Wing owners can use their on-board air compressor to add air to the trailer suspension. You can also use a tire pump or the air hose at a gas station. Bushtec offers an on-board compressor kit for other motorcycles. That allows the trailer suspension to be adjusted at the touch of a button. However you do it, adjusting the suspension for the load is a snap.
