I want to compare apples with oranges.
a tent on essentially a box trailer verse for example
a Toyota Prado for $60k that has expansive R&D, a computer controlled transmission, wonderful technology in passenger safety (airbags, traction/stability control etc) a hi tech V6 petrol engine with all sorts of computer controlled sensors, 2 x diffs, 5 x wheels and tyres, glass, power window regulators, sound system, chassis, panels, paint, dual zone climate A/C and the list goes on if you break the vehicle down into parts. Obviously economy of scale makes some of these parts cheaper but......
Break a CT down and you have box trailer, 3 x wheels and tyres, hitch, basic suspension, diesel heater for the top end CT's, 2 or 4 burner gas cooker, canvas tent, fairly basic electronics....
