We have triplet 6 yr old boys! They're used to car travel. We'll take the van down to SoCal every so often so they entertain themselves nowadays. Otherwise there's always their Kindles.
Our plan to drive from 2 - 4 hrs a day. That's according to google maps. I think there's one longish day at almost 5 hrs. And I don't have any back to back days where I'm doing more than a couple of hours each.
Thankfully the truck has adaptive cruise control which helps take some of the stress off from people slowing down in front of me. And I've got blind spot monitors.
I'm hoping this will be a fun family adventure. That's why I got the trailer!
