Hi! We are looking at what crew cab trucks can hold 4 car seats, safely. I currently have 3 across the back seat of my current truck, but as we are planning for the 4th, I want to be prepared for when all 6 of us need to travel in my truck, or when I take all 4 kids to school/daycare, etc. With that, I know that I can order a truck with a front bench seat and I know that my state law allows for my oldest to sit up front so long as all three seats in the back are occupied. My question is where on the front bench should the booster seat go - center or passenger seat (we still use a high back booster with the 5-point harness) and do any manufacturers have a tether or LATCH for the front bench?
