Three carseats fit in a pickup?

Lu

I've got two trucks: a crew cab Chevrolet 3500 and a crew cab Toyot

a Tacoma. We have two Peg Perego (Primo Viaggo Nida)

carseats, and I'm wondering if I could fit a third in the back seat or if I'll have to buy a new vehicle?

Are there any good narrow carseats, and has anyone else managed to get 3 in the back of a pickup? I want a third baby but don't want to buy another car 😐

Thanks in advance!
