I realize OP probably doesn’t care, but I find the differences interesting. Not too long ago, I just happened to park my truck (with grandpa cap) right next to the identical SUV. From the outside, the two looked like twins - same paint color even. And yet, when you peer through the back window, it’s immediately obvious how much less cargo space the SUV has. Even if you took the back seats out, there’s all this plastic trim that devours what should be cargo space. You’d never fit a sheet of plywood back there. And I don’t see why. Airbags & cupholders I guess?

I haven’t been able to even look at new vehicle prices in a while, but back when I bought the truck, it was literally half the price of the SUV. That’s an awful lot to pay for 2 rear seats and less cargo space. And yet, SUVs are everywhere here in America. Go fig.

I guess what I’m saying is that if you want more cargo space for less money - yes, the extra step of buying a tonneau cover or camper shell is totally worth it. Or was, anyway.
