I’ve seen several comments in this thread that conclude that it’s wasteful to have the truck bed when you are not using it. Going one level deeper, to the owner it doesn’t feel wasteful on a day to day basis because you forget it’s back there when you’re not using it. But it’s so handy when you do need it.
Former truck owner myself, I downsized to a car after moving to a more urban setting. It’s often on the weekends that I loathe not having to pickup for various furniture moves, gardening, etc. since I now have to borrow and friend’s or rent one.
