Just a quick update. We had a cookie dinner in the trailer, Smokey and I. Now he'll get in the trailer, but I'd say it was definitely a smell thing. He is snuffing the floor all over the trailer and raises his head in alarm.
But we've overcome it with cookies.
I'm never washing the inside of that thing again. Sweeping, rinsing, yes. Deep clean - never again.
Hopefully tomorrow I'll get him in there long enough to funk it up. :) Thanks for the reassurance!
