Long move, due date approaching

So on Saturday we're packing up our life and moving from Washington state it ny state. I'm due in 26 days but I'm not at an elevated risk for any complications. We're going to be driving 8-9 hours a day in a 16' box truck rental with our dog. Any advice to make the trip smoother? I already plan on drinking water constantly, packing lunches in a cooler, and getting our every hour to two hours to use the restroom and walk around a bit.
