F350 DRW CREW CAB
 

I WILL BE PURCHASING AUSED F350 DRW CREW CAB FOR USE WITH A TRUCK CAMPER.
FORD RECOMMENDS WHEN CARRYING SLIDE IN CAMPERS ONLY WHEN EQUIPED WITH OPTIONAL F-SERIES CAMPER PACKAGE.
HOW CAN I TELL IF THIS OPTIONAL PACKAGE WAS INSTALLED? ALSO IS THERE A DIFFERANCE BETWEEN THE CAMPER PACKAGE AND THE TOWING PACKAGE? AND WHAT DO THE PACKAGES CONSIST OF?
