Undercover Flex Ultra is a great product but its all about the dealer and installer which in this case is by far the cleanest shop I've every been in and that organization is representation of his work.

2nd one i've owned. My 2017 XDE titan had one as well. This one seems even better and has a more watertight seal and drain hoses that the other didn't have...
