If I could afford a second vehicle, it would probably be a truck. Between the two households, we could probably get enough use out of it to justify it, even if it wasn't big enough for a horse trailer (which is why I haven't brought the idea up with Eric. Mom would be unreasonable on the subject if a truck was purchased that could not potentially pull her precious mare around, despite not having a trailer or even the need for her own truck and trailer to get the horse where it needs to be)
I'd never want a truck for a primary vehicle, but given unlimited funds, I'd have a smallish sedan, an SUV and a truck parked in the driveway and I would be less than concerned if the truck rarely made an appearance on the road. It's one of those things, you may almost never need it, but when you do, you really just need a goddamn truck. There just isn't a great substitute and borrowing/renting is a PITA.
