I needed to rent a trailer for an upcoming bike trip, and the guy at the front desk was super helpful and friendly. He hooked me up with a brand-new trailer and a ball mount assembly and was able to accommodate my last-minute request to get the trailer for a week.
It's a bit off the beaten path in Sharpsburg, so I'm guessing they are not as busy as some of the other "major" locations. I'm definitely going here for my U-Haul needs in the future instead of the very hit-or-miss Washington Boulevard U-Haul location.
