Yah, that's the basic thing right there. There are definitely folks who need that kind of capacity, but for me the bother of hunting down someone with a big vehicle when I need it is much smaller than the cost of owning the capacity for myself, but rarely using it.
I've got my eye out for a cheap used car that's more economic, but it's not a big rush. I had a lucky break and was able to buy the truck outright (and cheap), so at least I've never had payments.
