Mouse moat for RV's in storage

That low section around the wall is on the outside with no end section. The pictures don't show any way to keep the water in the low section. Gotta be April fool's joke.

It's a metal wall that mice can't climb, a simple effective solution.
How hard can this be to figure out?

I believe it's the low section around the wall that gets filled, not the entire enclosure.

Sure it isn't April 1st?

I own the all metal building where I keep my RV. I put mouse poison out in small trays. They seem to like it. I find the occasional dead mouse on the concrete floor, so I just sweep him up and dump him in a large metal garbage can.
I rarely see a mouse or mouse poop anymore. Maybe a mouse was able to escape and tell his buddies with his dying breath.

I did something similar with Plexiglas in my screened in porch. The squirrels were always chewing a hole in the bottom to get in. A two foot high sheet all along the bottom but a stop to that. They can't get a grip to climb it.

This is a unique idea. That's all I'm saying. :)

Except maybe, a couple cats would be easier and cheaper.
It will be interesting to see if anyone actually uses this system and can tell us how well it works.
