Well, not actually the belfry but the fridge upper vent.
A couple weeks ago I washed the trailer and chased a bat off the outside of that vent, not thinking that he actually may have been living inside of it. Jump ahead to yesterday while winterizing the unit, did my usual inspection and to put a plastic weather shield on the vent. In two weeks, that bat had left me a good many little poops that look at first glance, like mouse turds.

Jump ahead to today and now it's suit up time for cleanup. The Province of Quebec has possibly the best site on cleaning bat poo up. Not fun - 9-1 bleach/water disinfecting solution, heavy gloves, 9 mil HF nitrile for me), goggles, face mask, paper towels, a wash with (antibacterial Dawn for me) then let everything dry. I'll finish with a spray of 90% alcohol. Yes, both 120 and 12 volt power is off.

For that cover, and since the 5er will be back on the same site next summer, those louvers have been covered with screening, pop riveted in place. I may add a couple vent holes to open more cooling area.

....and I thought I had experienced virtually everything while trailering. What's next!?
