Tarp Awning - Fiberglass-safe Fluid for Enhancing Suction Cups

[junglejim83]

Have you tried individual suction cups at the 'rounded' locations? Maybe it is the extended straight length of the dual cups which is not allowing either cup to follow the contour of the roof and adhere? Also, how smooth is your roof compared to the sides. Maybe a scrub down with barkeepers friend might get you there if it is a little weathered?

I am not doubting that the rounded contours of your trailer might make things more challenging (if possible at all), I am just trying to think of an alternate solution.

Jim, I haven't tried dual cups... these have all been heavy duty individual cups. I ordered several different kinds from Amazon (have quite a collection now). The roof is REALLY round. You can get an idea by looking at the roof:

I DID clean it, and also scrubbed the area (as instructions recommended somewhere) with alcohol. Also dampened/wet the suction cup, and tried soap also. They really would not adhere. I did not try barkeeper's friend, and the trailer has since been really polished by the DH with his orbital thing, so maybe I'll have better luck now.

It's also possible that these HF cups are much more industrial than what I was finding elsewhere, so I have hope! Also, I think the sides are much flatter than the roof, so it's possible I can use these to brace awning poles, even if they don't work up top.
