Have you ever had an idea that looked great on paper, but discovered it wasn’t so great when the idea was put into practice? We recently had this happen to us after ordering our Bundutec Roadrunner. Since we opted to go with a DC compressor refrigerator we decided to build the camper without any refrigerator vents. Our thinking was that they let in too much cold air during the winter. This is exactly what happened with our old Northstar Laredo. Huge drafts could be felt around the refrigerator during the winter. No matter how much insulation we stuffed around the refrigerator, the insulation didn’t really help. It was a vexing problem that was never really solved.
Of course, the Dometic vents in our old Northstar Laredo—which consisted of a standard refrigerator roof vent and a large refrigerator side vent—are required for regular absorption refrigerators to dissipate carbon monoxide and other gases. But the DC compressor refrigerator generates zero carbon monoxide. That’s one of its benefits. The only byproduct produced by a compressor refrigerator is heat. Retaining this heat to help keep the camper warm during the winter sounded like a great idea, but quickly fell apart in practice during the summer when keeping the camper cool is the name of the game.
We quickly reached out to BundutecUSA owner, Rory Willett, about the problem. Our solution was to mount a small refrigerator vent on the side. This side vent is much smaller than Dometic’s standard refrigerator side vent, yet would still provide our compressor refrigerator with the right amount of ventilation for summer use. It also looks better.
Of course, cutting holes in a brand-new camper takes a lot of courage. You have to be brave to do it. Being pretty handy, I considered doing the work myself to save another 3,000-mile round-trip to Iowa, but one wrong move and we would be screwed. The camper was brand-new and still under warranty. So we decided to head back out to Raymond, Iowa to have the new vent installed there. We’re glad we did. Rory’s team did a great job, cutting the needed hole and mounting new wood framing to make the new vent rigid and strong. Using block foam as framing is NOT a good idea because it compresses over time and can leak. It also isn’t as strong.
So far, the new refrigerator vent for our Dometic CR1110 has worked great. What about those troublesome winter drafts we mentioned earlier? We’ve eliminated those too by using a piece of rigid foam in the vent. This was Rory’s idea. We simply insert it before winter and remove it before summer. The key is finding the right kind of foam, one that is bendable, yet won’t crease or weaken over time. It also has to have enough pliability to allow you to insert your fingers in the frame to remove it, yet provide enough insulation for it to work during the winter.
Do you have one of these vents and have a winter draft problem too? You might want to try using one of these foam inserts. Not only does it help control temperatures inside the camper, but it also eliminates bug intrusion inside the camper—read mosquitoes, spiders, and mud daubers—something Duncan Crawford wrote about at length in a previous article published here. So far, the foam insert has proven to be one of our best winter mods and one of the cheapest and easiest too! If you already have the vent.
