Whitehawk Plastic Bumper: Attaching idea?

[travelingjw]

In 4 years we've now lost both plastic bumpers over the wheels on our 2017 Whitehawk. We have no idea how we lost the first one but on this one I noticed that the area held by the screw had cracked. I duct taped it to hold it but we had some high winds and lo and behold, the bumper is gone. The only ideas I have is to cut some custom holders (see photo) and/or to run some Quad or Dicor inside the bumper and maybe hold it to the side of the TT.

Don't see photo?

I had one that was flapping and epoxied a bracket on the fender and secured it to the down bracket that Jayco had installed with some tie wraps. It has not moved since then.

Not knowing what the backside of the flare/wheel opening molding/bumper looks like this suggestion may not work for you. If the backside edge is flat ( 1/2–3/4 of an inch) the aftermarket flares used on pickup trucks use quality two sided tape along with the screws. 3M makes very good two sided tape. Make sure both surfaces clean. I would put the the tape on all the flat surfaces. Try to do it as close to one piece as you can , you don’t want gaps that will show between the flare and body. I hope this helps.

I assume you mean the plastic fenders.

I think it's the constant wind that, while driving, gets into the gaps and continually pulls at and/or vibrates the fenders and ultimately works them loose.

I was worried about this, so I used black caulking to seal up the gaps and make the fenders more aerodynamic. The caulking doesn't act as a glue, but rather it helps to prevent the wind from vibrating the fenders and/or pulling at the retaining screws.

So far, so good. I check them each time out. If the caulking starts to crack or come loose, I fix it before each major trip.

I replaced a fender on my Whitehawk last fall. Dealer was the best price ($125) and perfect fit..no trimming...and in hand in less than a week. The material used for these is very thin and I used rubber backed washers under the screw head all the way around both fenders. It makes for a larger surface bearing the stress and hopefully doesn't pull through as easily.

I put rubber washers under the screw heads, speed nuts on the screws that are exposed on the back side, and seal the crack with ultra black RTV.

On our last unit, I pulled the skirts and crammed butyl in the screw holes and made a butyl bead to seal the back edge. That worked really well, too. I also used the rubber washers and speed nuts on that unit. It really helps.
