Good questions.
I think the organizers are nice for stuff that I don't want to have to search for (and wound't need to take into a motel). Like a tire gauge or a flashlight. I also have some bungies and a cargo net stuffed in pockets so they don't get all tangled up.
I still have not decided what all will go in the organizers. But it is nice to have options.
I also have bag liners that I use to take into the motel. They are Bestem liners and are real nice.
