So I just removed the entire bike rack slide out assembly from my 2010 Laredo 5th wheel. It weighed in excess of 200#s and was mounted by just 8 rather small bolts. Replaced it with a Curt class III hitch mounted to the frame with 8 grade 8 bolts. Going to use a hitch mounted bike rack from now on. Much better setup and now the trailer is roughly 130# lighter.
