When my 4 kids were young, we always had a full size conversion van. This was back in the 90's when they were very common. Traveled to 46 states with 4 kids comfortably. No substitute for the personal space on long trips. I shudder to think of traveling with my gang in a crew cab pickup.
They are still made, just not as common as they used to be. Rated to tow 10K, they make a nice tow vehicle. They do like fuel. 13 mpg. I found that a small price to pay for the travelling comfort. We truly had some priceless travels with the kids. In my opinion, the only way to go with that many kids.
