I want to say my 28DSBH is around 6,400 loaded. I can't remember the actual weight of the unit with the installed options but I'll be bringing it home Thursday so I can give you a better idea then. You really should have a problem. We towed it from Pa to Long Island, about a 4 hour trip across two NYC bridges. No trouble at all.
