Motorhome
Yakima states the 2" StepUp is RV tested and approved at 43.5 lb per bike; the current hitch-fitting guidance and the exact RV receiver limits still control.

Yakima StepUp 2": RV compatibility
Current two-bike platform rack whose dedicated 2-inch version is RV tested and approved by Yakima at a reduced 43.5 lb per bike.
Short answer: Yakima allows it on motorhomes only with conditions. Fifth wheels, travel trailers and flat-towed vehicles: not confirmed by current manufacturer wording.

Manufacturer guidance by RV use
Fifth wheel
The verified current sources say RV tested and approved but do not separately identify fifth-wheel use. Verify this application directly with Yakima.
Travel trailer
The verified current sources say RV tested and approved but do not separately identify travel-trailer use. Verify this application directly with Yakima.
Flat-towed vehicle
The verified current sources do not separately confirm rack use on a flat-towed vehicle.
Evidence note: Yakima’s current product page covers both hitch sizes, but the current hitch-fitting guide marks only the 2" StepUp as RV approved. This record intentionally does not transfer that rating to the 1.25" variant.

Conditions that can change the answer
- This RV rating applies only to the dedicated 2" StepUp; the 1.25" version is not marked RV approved in Yakima’s current hitch-fitting guide.
- Maximum 43.5 lb per bike for RV use; do not substitute the 65 lb road limit.
- Verify compatible receiver class, tongue-weight capacity and all Yakima clearance measurements before installation.
- BackSwing and StraightShot compatibility on the product page is general vehicle compatibility; those accessories do not automatically inherit RV approval.
Before you travel: confirm the exact rack variant, current manufacturer manual, receiver and hitch rating, bike weights, permitted adapters/extensions and any reduced RV-specific load limit.
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.
