No problem about the questions. Sorry for the delay, I was on another trip off the grid.
I will add a separate post for the cargo net, but I found when adding the wood strips for that the screws that were intended for studs actually held very well no the wall material. My stud finder did a poor job, and if I made a hole already I just stuck with it. I used the wood strips so I did not have to pepper the walls with holes (many D-ring were needed). See the other post.
