Hi, I am moving from New Hampshire to Toronto with most of my stuff and just realized that the 5x8 U-Haul trailer I rented is not going to be enough. Luckily for me, the same location has a 6x12 cargo trailer that is available for the dates. I asked them at U-Haul if with the hitch they installed (Class 3 hitch, Max weight: 5,000 lbs., Max distribution weight: 6,000 lbs.), I could tow that 6x12 trailer (Max load: 1,800 lbs. Gross vehicle weight: 2,700 lbs. max, Empty weight: 900 lbs.) and they said they don't know.

I am looking for someone to advice me if this is a good idea or not? The trailer comes with a surge brake, and the route I am going to be taking will not be exactly flat. I am probably going to be loading my my trunk with some suite cases as well

Thank you very much!
