Hey, @MacKenzie78 , I'm going to hop in here because I have sometimes lent my camping equipment to my own guests. My strong advice is don't do it.
Camping, in itself, is hard on things, and it's made worse by people who don't own those things. Thanks to experience, the only thing I will lend at this point is a campstove, and it absolutely is not the campstove I use myself when camping.
Outfitters are set up for equipment rentals with insurance and replacements and a great attitude about damage, because it isn't their personal stuff: it's just business. Maybe consider being an outfitter? It sounds more like what you want to do.
However, I just did a search, and a guy called Joe in Arizona is advertising his camping equipment on Airbnb and getting great reviews. The search terms I used were "camping equipment airbnb". I'm not going to paste his URL here in case he doesn't want that. Anyway, try that and it might work better for research than asking here in community centre. (Although asking is always good!) It's just that I picture Joe being too busy mending ripped tents to have time for a host forum. 😉
