                                                          If you want a Ford Van to tow a 40 Foot Camper, you'll need an E350. Consider getting the E350 with a Diesel engine offering as well.  This setup of the E350 Suspension and the Diesel engine will provide the overall strength that will be required to tow such a camper.
