If you have a ladder on your RV, you may want to consider the Stromberg Carlson LA-102 1-Inch Bike Rack. The benefit of this type of bike rack is that it frees up the receiver on the back of your camper to pull a cargo carrier instead of holding a bike rack. You simply secure this rack to the ladder, and the manufacturer assures that you won’t hear any distracting rattling noises.
The rack has a weight capacity of 50 pounds and can carry one or two bikes. If you want access to the ladder, simply remove the pins. The bike rack is aluminum, which matches the construction of most RV ladders, and it’s rust resistant The rack is versatile in that you can hang your bikes either vertically or horizontally depending on the location of the ladder. Overall it’s sturdy, easy to install, and folds out of the way when not in use. One downside is two of the straps are hard rubber/plastic with very little stretching capability, so it can be difficult to clamp down your bike.
