As Bob suggested I initially wondered if it may have been due to wax or Scamp surface "cleanliness".
However the adhesive was pulling away from the gutter material and still stuck to the Scamp.
I will try the dental floss approach for removal.
I am now thinking the radius of the bend may have been too extreme for the RV gutter and the stress of the bent plastic may have been the issue.
Every day Scamping brings a new adventure. Some more pleasant that others LOL.
Many many great new tips and once back home we will add tire pressure/temp monitors, bearing buddies for wheels, and a few more things.
I also need to repair awning
that collapsed early on the trip due to ignorance (operator error) with not enough slope for heavy rain run off.
Got too heavy and bang down she fell. Took out the center support rib and plastic swivel bracket for one leg. The Fiamma importer and service center in Orlando was absolutely fab and sent replacement parts ASAP.
I need to remove the entire awning from the Scamp and straighten the forward aluminum mounting bracket. I may need new sealer around the large bolts through the shell if I remove the whole thing. I will also need to remove the awning fabric so I can straighten the front long support (with logo etc.) that is bent a bit as the awning does not retract all the way back in the holder nor is the leading part of the fabric taught when extended.
As DW indicated what a great shared hobby!!
In other words FG trailer maintenance. She has many new innovations learned on the road from all the wonderful folks we met.
Guess we need to "suck it up" and head north to the cold like it or not in the morning.
