An RV bumper cap seems like a simple accessory, and you probably don’t worry too much about what’s happening with your bumper caps. But they’re more useful than you might think. RV bumper caps serve two important purposes. They’ll help keep your RV’s sewer hose securely in place when you’re packed up and on the road between campsites. And these simple caps will also protect your RV against pests like insects and rodents, preventing them from crawling inside and creating nests. Without bumper caps, you can lose your RV sewer hose along the road, wind up with wasps’ nests, or discover an infestation of pests. So, if you’re in need of a new set of RV bumper caps, you’ll want to check out the following top choices.
