Question on Trailers

So I have a long distance move (about 10 hours) that I think i will do by myself as I do not have too much stuff.  I want to get the biggest trailer.  Now, I'm thinking of driving down with the trailer and driving back , dropping the trailer off at the same location.  As to save me money.  Do i have to disclose  to UHaul where I'm going? Or they dont care as long as they get their trailer back in 1 piece?
