Picture of my $8 custom stainless steel grill.
Here is a picture of my custom $8 stainless steel grill. Its 4 "Gutter Guards" from Home Depot. I cut to fit, bent the top and bottom to mold to the inside of grill, removed the plastic chrome cover from factory (4 bolts) and zip tied new grill in several spots about 6 or 8 inches apart from each other. I did use some "Gel super glue" on the upper part of top grill only since it seems a little loose (no place to zip tie on the very top and very bottom strips). Its been in place for 3 mo or more and still looks great. I spray painted some shinny stainless steel radiator supports for the AC condenser so its totally black behind my grill.
It adds more of an upscale look to my RV plus will protect radiator from big bugs and small birds/rocks. I have been watching my temp gauge on long uphillís and I am happy to report NO change in the needles location (But I dont tow anything right now). So I donít believe I will have anything to worry about for my application. If you run in an area with mega bugs you might want to scrape or rinse them off to prevent overheating if that is your concern. I find the garden hose with garden sprayer washes most bug out just fine. Or you might use a can of compressed air on the road.
