Congrats on the new motorhome Edward! SnapPad doesn't have the 2026 Allego Red 38 KA in their system so I don't know what size your jack feet are. However, we have a few options that will work with the HWH leveling systems. What you'll…

We have had a similar question to this come up and we were able to determine that the number AS-13 M-VDO449 that you listed is stamped on the vent cover part #BVD0449-A01. If you are looking for the entire fan setup and not just the cover you would…

Hello Lee, thanks for reaching out. If air won't go in at all it could be a bad/clogged valve. You could also have a major leak somewhere. Have you tried a soap test to see if there are any leaks?
Welcome back Chris. The original MaxxFan 5100k fans couldn't handle the extra voltage from Lithium batteries and the boards would burn out. A green light would come on and beep after the fan runs for only a few seconds, which sounds like exactly…

RV Vents and Fans by Polar Hardware
Polar Hardware rv vents and fans make it easy to manage airflow. Choose adjustable designs with a butterfly valve or a lever you can close in heavy rain, or go with constant-flow louvers set to face downward to help divert water. For cooler interiors, place one vent low up front and another high at the rear; just know these vents won't pressurize your trailer or filter dust.
Yes, they work well for moving hot air and routing AC makeup or exhaust air. Keep the vent path as straight as possible and maintain a low-profile orientation to reduce drag. If you need constant airflow, you can leave the damper open or omit it. Check for baffled or down-facing louvers to help ventilate while minimizing water ingress.
No, they do not create a pressurized trailer or filter dust. They are designed to allow airflow and some have an adjustable butterfly valve to set how much air moves. Mount louvers down to help with water, but expect outside air to enter. If dust is a concern, consider location and how open you set the vent.
Use one low in the front for intake and one high in the rear to exhaust hot air. That layout promotes cross-flow and helps move heat away from equipment. Aim the exterior louvers downward to reduce water entry. If maximum flow is the goal, note that a closing device can restrict airflow, so set or configure it accordingly.
They can help divert water when installed with louvers facing down. Use the interior lever or butterfly damper to reduce airflow during heavy rain. Place one vent high at the rear to expel hot air and one lower at the front for intake to improve cross-ventilation. Seal the perimeter with a quality silicone and use appropriate wood or sheet metal screws.
