The old Caravans are easy to fit with roof top tents, just fit aftermarket crossbars that
use towers to fit in the raingutters. Fortunately when Dodge did
away with raingutters they introduced an excellent factory rack
rated at 150 pounds. The Durango, for example, uses two crossbars
with either Thule's excellent Tracker II system or Yakima's Railrider
A great combination for traveling - highways OR backroads.
