We have a 2013 scamp. We are looking for ways to put shelving in the bathroom and closet. We only have a Porta potty and really don't need a hanging clothes rack. We store a camp stove and small collapsible table. Would lie to put in shelves without putting holes in the fiberglass.
Pic would be helpful for those who don't know Scamps. If the bath is fiberglass you could tape shelf supports in place with 3M VHB tape and screw them into the bottom of shelves. Poster board is good for making templates.
