No they actually serve a purpose.
I ran my Caravelle for 18 months with its factory fitted one on , then when it was due to go to the body shop I took all the bolt on bits off and drove it 80 miles , it made a difference on the motorway for sure and the wind hit the van much harder
it definitely makes a difference as it limits air getting under the front and lifting it thus lightening the steering, most noticeable on converted panel vans that have 19mm antiroll bar (ie most UK campers), helps eliminate draught steer too
Mines still in one piece despite numerous wild camping expeditions, no problem with speed humps or goin on and off ferries. Just improved handling on the motorway. As for fitting I used stainless self tapping bolts . I wouldn't suggest riveting it as if you ever want to remove it you will have to drill it off.
Just come across this post, since buying my camper always felt unsafe on motorway especially certain parts of M27 even driving at between 50 and 60 felt as if I was fighting against a side wind, does fitting this spoiler alleviate this.

Think you’ll find it’s a rivnut gun that’s suggested. Holes are already under the front, rivnut gun makes it easy to insert a captive nut then just bolt the spoiler in place.
The side sections under the step will need either self tappers or drilling & bolts.

Yes it improves the "auto lane change " character somewhat , it’s changes the air flow and puts more pressure on the front of the van and replacing the steering and suspension bushes will also improve it .
