When you have basement air the ceiling fan plays an important part of the heating and cooling for your RV. I have a slide out that covers the ceiling fan when in the travel position. So research is needed to get the right fan. I purchased a low clearance fan from the Internet but the original had better clearance. What the video and see the pictures below.
I just made it. Now I need a trip to see if the cradle mounting will work while traveling. If it doesn’t I have a fix ready. Etrailer.com has an RV ceiling fan at a reasonable price but I had already purchased this one. When you research your fan they don’t tell you anything about clearances because they don’t disclose it.
