I finally got around to installing my HWD this morning. This, of course, is the Haygarth Water Deflector. I actually got this from Haygarth a couple of years ago for another coach but I ended up selling the coach before I had a chance to install it. This will give me some peace of mind.
I never had a problem until about this time last year when I was heading for Nacogdoches. We drove through a torrential downpour for what seemed like hours. When I got parked in MOT's lot I saw water pouring out of my air cleaner canister. I pulled the filter and it was completely soaked. I dried it out with a couple of fans and reinstalled it. I'm wondering though if the water affected the filter. It got a lot dirtier than they usually do in about a year. Anyhow, good to go now.

Jor, looks good and WILL cut down water intrusion almost 100%. I had the same issue with mine and dried the filter out overnight as we were on the road from Yuma to S Diego when we hit a heavy wet snow fall. I decided then that I had to do something and that design was born. Common sense really and I have never had that issue again and have driven in some wild wet weather since.

Sure be interested in how THAT COOL IDEA was installed & how it works? ^.^d
Here's Haygarth's write-up on BeamAlarm, Mike.

Check on the Donaldson website to find your engines intake CFM, I can almost guarantee you will be sucking in snow and water with those tiny slots. My coach breathes in about 600 CFM under load and any velocity over about 500 fpm will transport water droplets. Grab the Dremel and cut out all of the middle slots to cut the velocity. Your coach will love you for it, and perform better
I'm very happy with my HWD.
Just got mine made from an aluminum metal shop in Portland. He will make 5 for a group (5 units at $95 each, total $475, plus shipping, if someone wishes to buy 5. Just making one at a time, he said he can not do. Send me a personnel message and I'll give you his information. He is a rv owner, a dependable person.
I plan to mount my replacement backup camera to mine and will post pictures when done.
If you do that, how do you keep out the varmints, birds building nests, etc? No doubt air flow to the engine will be improved until the nest is built.
Not sure how feasible it would be but this could be done at the same time you install a resonator but I would suggest you modify
the intake to the driver side setup like many are.Jerry,is yours on the side?We do not drive in the rain but when we have I have
never gotten one drop of water near the air filter with the side setup.Another note,my air filter is the one where the air goes to the
inside and goes to the engine from the outside.You guys that have had wet air filters are lucky as hell it did not fall apart and do
engine damage.Will research the difference between the 2 styles and see what's up.
John44 , are you sure your filter from the inside to the outside to the motor? If so what filter number do you run?
