We recently purchased a 2014 Class A Winnebago Vista. Short miles and clean. One irritating problem is the running light lens covers have been falling off. Two were missing when I bought it and I've lost 3 more since. The certified RV shop said the lens for the one missing on the front above the windshield is a discontinued item. He found me one on eBay for a premium price. Today I drove it out of this shop 20 miles to my destination and one of the side lens was missing when I arrived. My certified guy is tenured and reputable. Does it make sense these top front markers are a discontinued item? Is this a freakish thing happening to my other lens covers or have others heard of this? I drove a class C for 12 years and never lost one ......We're customizing a little and are hoping to post pictures soon.
