JCJ Enterprises M-1800 Mud Dauber Screen for Truma and Alde Water Heaters 110 mm (Airstream)

I install this on my 2023 Winnebago Travato 59KL in August of 2023 after purchasing the van in April same year. I've put almost 10,000 miles on the RV and the screen has stayed exactly where I placed and installed it.The installation was fairly simple, although some may find it a challenge. The included install tool was a huge benefit.I did make one slight modification by taking a rubber tube, cutting it to the desired length then slitting it length wise to install on the surface edge of the screen. My thought was to provide some added protection, keeping the metal screen base from rubbing the paint off the van body. Seems to be working very well, and as you can see in the photo, blends nicely.

Had a problem with mud daubers getting into my Truma exhaust. This screen is worth every dollar

I purchased this item in Fall 2023. It is a quality stainless screen that did not show any indication of corrosion over the eighteen months our screen was in use. . We've been on the road for the past three weeks.. Today the screen was gone when we arrived at our destination. Admittedly we did hit some rough patches of road during our five hour travel day. I'm wondering if the installation springs lose their tension over time after repeated heat/cool cycles from heating system use. This screen becomes an expensive purchase if there isn't a permanent, reliable mounting system to keep it from falling off. I would consider purchasing this again if the manufacturer provided more than two flimsy springs to hold it on.

I was able to easily install on my travel trailer which has a Truma combination water heater and furnace. Though it talks about 110mm outlets it really does not tell how big it is in diameter. It is about 127mm in diameter, so it is a little bigger than you might expect. For the premium price paid I would have liked some sort of soft edge material between the screen's metal edge and my fiberglass trailer exterior. I ended up slitting a small, approximately 1/8", rubber windshield washer hose and installing it around the edge of the screen. Good fit and it protects the side of the trailer. The rounded ends of the springs were a little hard to attach to the screen so I bent them slightly to make them easier to get though the screen grids. Seems to have plenty of pressure to hold everything in place. Otherwise this was a good quality screen, though a little expensive, that should last for years.

The media could not be loaded. I’d love to spend a few minutes with the engineer who thinks these springs were a good match with this cover. This is the second one I have installed and it took a good 30 minutes to just fasten the springs to the shield. You folks really need to be more considerate for older folks. I would recommend finding something else vs purchasing this pos.

This is a perfect fit for the Trumi Combi water heater/furnace on my Thor Motor Coach. Yes, the round end of the included springs is difficult to attach to the screen, but a little adjustment to the end with a needle-nose pliers easily fixed that issue. I did add 1/8-inch edging to the metal edge of the screen touching the van surface to prevent any metal-on-metal wear.

Strong screen. Fits my Truma Combi exhaust on coachman van. I think it should include rubber gasket to protect paint. I fabricated my own. But it keeps the pests out of the exhaust.

Screen worked as it should, however it would be better if it came with a rubber gasket.
