Using the Yakima LongHaul bike rack is easy. First, make sure your RV has a 50mm (2”) hitch receiver. Assemble the rack as per the instructions, which should take about 5 minutes. Once assembled, attach the rack to the hitch receiver on your RV. Then, place your bikes in the SuperCush ZipStrip™ cradles. The anti - sway design will keep them in place. Use the LockDown™ cable from the SKS security package to secure the bikes to the rack and the HitchLock to lock the rack to the RV, all with one key. When you're done using the rack, fold down the arms for easy parking and storage. Note that the rack is only suitable for 50mm (2') hitch receivers. Each bike should not exceed 17 kg, and the total weight of all bikes should not go over 68 kg. To maintain the rack, clean it regularly with a mild soap and water solution. Check the locks and connections periodically to ensure they are in good working condition.
