Why exactly can you not pull a semi trailer with an RV hitch? Because it tilts side to side and runs a risk of not having clearance at the tires?
That's disappointing news... I was really hoping to use a standard dry van because they are readily available and I'm on a tight budget.
I guess that I could do a major conversion on the dry van to make it work. Notch out the front and install an RV hitch. Maybe?
