Thanks, everyone! I did see the Pictures of Mods thread, but it seemed like there were spring-loaded ones like shower rods and solid dowel ones, so I thought I'd ask. Linchat, thank you especially! I was just at Lowe's measuring and puzzling out ideas for shelves and to build a passenger-side console. I looked at shower rod rubber ends for this project, but didn't think to look for furniture boots- perfect!
I've been reading the forums night and day; we're equal parts nervous and excited to spend most of the summer living in our FR3- definitely grateful for such a helpful and welcoming community!
