If the filter on your Valterra RV Vent Ceiling Register # A10-3361VP is dirty it is possible to remove and wash the existing filter. Unfortunately, a replacement filter is not something that is offered. If you need to replace the filter because it is worn out or damaged you will need to replace the entire vent. view full answer...
I was able to verify with Horizon Global that the Rola Swinging Enclosed Cargo Carrier for 2" Trailer Hitch # 59109 is safe to use with your 2022 Tiffin Open Road Allegro.
The Yakima BackSwing Swing Away Hitch Extender # Y02483 cannot be used on your RV per Yakima.
Since the Rola cargo carrier integrates tail lights you will need a Pollak 7 Pole to 4 Way Connector Adapter # PK12716 unless you already have a 4-way on your Allegro. view full answer...
