Anyone using a portable toilet tank as a drainage reservoir?

I keep a veiled chameleon in a screened enclosure in my Denver apartment, and the drainage situation has gotten old. Right now I have a plastic bin under the cage with a bulkhead fitting, but it fills fast and hauling it to the tub is a mess. I saw a portable RV toilet with a 5.8 gallon holding tank online, and the sealed tank and easy-empty design got me thinking it could work as a drainage reservoir instead of a toilet. My concern is whether the plastic is safe for the water that drains through the cage, since it's meant for waste, and whether the fittings would hold up to daily misting runoff without leaking. I also worry a tank like that could be overkill for one chameleon and harder to clean than a simple bucket. Has anyone here tried adapting an RV-style holding tank for drainage, or found a better sealed option for a small apartment setup? I'd like to hear what's worked for you.

Can you post some pics of your enclosure? How often and for how long do you mist for? In all of the various set ups I’ve had, I’ve had zero issues with excess water drainage. I recently took down my bioactive set ups and now just have a few potted plants and a plastic substrate tray. I expected I would need to be pulling out my wet vac, but the water evaporates in between mistings.
