Russ and Tina De Maris posted this early "fifth-wheel" on their blog at http://weirdrvs.rvtravel.com. "Sorry," they write, "we don't have much more information on this one. The photographer who caught it wonders if the tow vehicle might've been a hearse in an earlier life." Or maybe an ambulance. Perhaps RVBUSINESS.com readers can help solve the mystery.
