Hitch-Mounted Hanging Bike Carrier (4 Bike Capacity)

This is simply because the ride at the rear of an RV or Trailer is significantly rougher when compared to the rear of a standard passenger vehicle. The reason for this is that the rear of an RV or travel trailer is typically extended well beyond the rear axle, which results in a see-saw like action when driving down the road that in turn creates a lot of extra movement on the hitch and bicycle carrier.
