A method comprising the steps of:
- lifting a front flatbed trailer section of an extendable flatbed trailer relative to a rear flatbed trailer section of the trailer with a first roller wheel of the trailer;
- lifting the rear flatbed trailer section relative to the front flatbed trailer section with a second roller wheel of the trailer;
- wherein one of the steps of lifting comprises the step of moving a first section of a first support assembly relative to a second section of the first support assembly;
- limiting travel of the first section relative to the second section with a portion of the first section within an elongated slot of the second section;
