Roof vents and backup lights

I have a 2005 Dutch Star, my roof vents have become brittle and need to be replaced can't believe the plastic has become brittle in 8 years, what is best replacement.

Also I am looking to replace my back up lites, the clear ones Newmar part 50538 @ $ 90 bucks, trying to find original supplier, should be able to buy cheaper, mine are discollered.

Also I burn out porch light every year, looking for cooler bulb?

Thanks Bob Niles

Same thing happened to our MA. Bought two shrouds from our local RV supplier and painted them with paint from Sherwin Williams. Have a look at the pics in my post. I also took a video to show how brittle it became. I suppose it's all about how much sun exposure our motorhome is getting. Probably worst if the shrouds are dark. The installation is fairly easy.

I assume you are referring to the vent covers and not the AC covers. You can install the vent covers that are available at most RV Stores. Then, treat them with Aerospace 303 Protectant. In ant case, 303 will keep all your outside components looking great. Good place to find it is Amazon.com

As for lights, check out this site. I just got new rear marker lights for my coach from them and they are great to deal with.

Oops... I miss-read the message... On the other hand I believe everyone should test the condition of the AC shrouds especially on older models. If you hear cracking when you push on them lightly they're probably brittle. I for one believe in "if it's not broke, don't fix it". But, it's very dangerous when they break off on the road.

I buy roof vents from local dealer and there are 3-4 screws to R&R the vent then add some Dicor over to reseal. The A/C cover cracks can be fixed w/ fiber glass cloth and 30 minute epoxy applied over the cloth or buy new ones @ $125/ea. Older coaches do have constant maintenance and repair issues.

The oil leeches out of the plastic and makes it brittle. Try shooting a couple coats of clear coat paint on them before you install them. Maybe this will add a couple of years of use to them.

Fantastic brand has a 2 layer insulated replacement if that is your brand.
We second the 303 aerospace protectant and our 1999 dark smoked vent covers are still going strong with 6mo / year in the Texas Valley sun. The other 6mo it does sit inside out of the sun. We even use the pillows in the openings which can add to heat buildup but 303 every 1-2 months has worked for us. Actually wish ours would crack so we could replace with the 2 layer type.
