Question:
I have a 2021 Riverside Retro 135 that needs a 1/2 moon hub cap. Which one that you sell is the correct fit?

Expert Reply:
The Americana Baby Moon Trailer Wheel Center Cap # AM90086 you found is likely to be the only baby moon cap we have to fit your 2021 Riverside Retro 135. While I cannot see exactly what parts your camper had from the factory I do see it came with 14" wheels. You can verify this is the correct size for your camper by verifying it has the same 9-1/4" inner diameter as your current hub caps or measuring where the tabs are on your wheels is the caps are both gone.
