In the back of my truck, I routinely have: Gas cans Used oil containers Lawn and tree equipment Gravel Sand Soil Mulch Trash/refuse/recycling Mountain bikes While a floor liner would certainly help, all that stuff is still going to destroy the inside of a family vehicle pretty quickly. And taking precautions to prevent that from happening means being extremely diligent about cleanup, whereas I don't care one bit if the bed of my pickup truck is dirty.
