We had a Trek several years back and we had some clamps that fit on the rail when the bet was all the way up.We just put them under the bed rails after we lowered it for sleeping.Not sure where to get them,but there use to be a site called TREK TRACKS that was for Treks only and had a lot of great imfo.
