>If you really need something bigger renting a trailer or truck is dirt cheap

It’s neither convenient nor cheap to rent a trailer in much of the US. Major cities have options, rural areas less so. Full disclosure I have a mid-sized pickup, but I recently looked into renting a trailer for a landscaping project that was above the weight limit for my truck. First issue I ran into was that there were not any trailers available for rent anywhere near my location. Second issue was that after factoring in driving distance + rental cost + dump fees, it was ~ the same price just to pay a junk company to haul the materials…and it was not cheap. Anecdotally, my pickup was cheaper than most other vehicle options at the time I bought it, my commute is short (so fuel economy is less an issue), and as a homeowner I use the bed to haul something at least once/month (Unfortunately kei trucks weren’t available at the time). So the cost/benefit/convenience factor of owning a truck over renting a trailer works for me. YMMV.

Yeah, I cannot speak for rural US as much, I live in a large metropolitan area, and I would estimate around 1/5th cars here are pickups. You can rent a truck from Home Depot for as low as $100 a day.
