Who will take donated RVp-related items

I used to have a popup camper that I donated to a Chicago-area charity. I now have a lot of accessories that I would like to donate, but don't know who would take them. We no longer to RV camping.
I'm talking about items such as water container, grey water container, BAL leveler, BAL chocks, hoses, fittings, etc. I even have cookware for inside use.
Anyone know who would want these kinds of items, used and donated?

Thanks.
