Not sure which model Vengeance the OP has but my -25V has a sloping floor in the very back. There is plenty of clearance below my frame, which is lower than the Street Glide. I've also loaded with the jacks retracted. The Vengeance is pretty forward-heavy.
As far as the WD hitch goes I'll defer to someone with a lot more knowledge than me. I'm still trying to figure it out. With my Harley loaded the hitch weight drops from 980 to 900 pounds.
