Donโt know what it is. Brand new trailer and thereโs some brown gunk. Looks like a spilled chocolate milkshake. Itโs not poop because I havenโt pooped in it yet and it didnโt smell.
Wet rag, see if it comes up. then a cleaner like 409. then try denatured alcohol mixed 50/50 with water. then wd-40 then paint thinner then acetone

Yeah. Probably. I did do a review on wednesday and didn't see it. I picked it up today and all we did was hitch the trailer and I left. I noticed when I got to my parking spot.
If it's brand new I would take it back to the dealer and let them deal with the mystery. Did you do an inspection before you took possession of the unit?
