A couple converted a Ram ProMaster camper van themselves after receiving a $20,000 quote for insulation and wiring alone. Steve, a retiree, planned the interior by watching YouTube videos and taking notes. The van has 600 watts of rooftop solar, a 12-volt refrigerator, a separate small freezer and a two-burner propane stove. The total cost of the conversion was not disclosed, so the exact savings remain unknown. Steve said the couple had not paid for camping in the year before filming.
