Here is a list of car seats that'll fit 3 across in a F-150. https://www.thecarcrashdetective.com/3-across-installations-f-150/ https://www.thecarcrashdetective.com/3-across-installations-... Several on that list will fit children up to 57-62" in height and up to 120lbs. This (https://www.thecarcrashdetective.com/diono-radian-r120-review/ https://www.thecarcrashdetective.com/diono-radian-r120-revie...) seat will fit 3 across in my Subaru Forester, a Honda CRV, or a Fiat 500L, and support a kid up to 57" tall and 120lbs in weight. It might be more convenient to have a three row SUV with three kids, but the idea that you can't fit 3 seats in these cars is nonsense.
