Our rv covers come standard with all of the same components as our carports.  Our base height is 12′ on the eave but can be extended to 14′.     Unlike most of our competitors, however, ours come standard with 3′ vertical sidewalls as well for extra protection.   We can attach to your concrete slab or concrete them in the ground.  Take comfort in knowing that your investment will be protected from the elements with Bedrock Structures.
