All, thanks for the replies – good to know I’m not the only one thinking about this. We’re still undecided at the moment and our maiden voyage is just around the corner in July. We’ve pushed off installing the full electrical system and headliner so we can focus on achieving minimum capability for the camper. I agree the Velcro would have to be glued, which is a disadvantage. I think strong double-sided tape is the way to go.
