This isn't a car and truck site, so I will cease and desist, for a while, after this, but I have this nagging curiosity. Ford, Chevy, GMC, and Dodge all claim significant profits from selling more pickups instead of cars (sedans and coupes and that sort of thing). And SUV's are often built on truck platforms. I can't figure out what the major savings would be between a sedan and a pickup. Many pickups now have a full front and back seat and interior treatment. Why does the truck bed in the back represent a significant savings in production? It seems the whole package would usually be heavier duty, more metal and bigger engines. How does this result in less production expense and bigger profits? I'm usually somewhat good at figuring out this sort of thing, but I am stymied.
