Conditions that can change the answer
- RV/Travel Trailer use is limited to two bikes.
- Single base: first two tray positions are published at 100 lb each.
- Double base: the first tray is published at 100 lb and the second at 75 lb.
- Do not use a Cargo Add-On as though it inherits the base rack’s RV rating; 1UP USA lists the Cargo Add-On as not RV/Travel Trailer rated.
Do not treat this as a safety certification. Your regional product version, vehicle, receiver, rack configuration, bike weights and current manufacturer instructions must all be within their own limits.
