I was up on the ladder today doing some maintenance on stuff on the Sprinter roof and I noticed that the forward foot of my Fiamma awning mount is digging into the roof. The aluminum foot has dug through the paint and into the metal and I can see paint blistering around the area indicating rust under the paint.
I’m leaving on a trip tomorrow so for now I painted the area with Corroseal rust converter and added a 1mm thick strip of PTFE material under the foot to prevent it from causing further damage. It looks like there is supposed to be some rubber material under the foot to protect the van body; either it was never there or it got stripped out by low hanging branches I passed through.
Just a cautionary lookout to anyone who has their awning mounted to their frame rail using this Fiamma awning mount.
