How old is he? Any reason (outgrown, etc) why he can't stay in his harnessed seat for the trip this year? You may have to rethink your plan of driving overnight as kids get older. We do 8 hour trips with kids during the day without too many issues.
Sorry, we have the Turbobooster not the Nautilus! (What am I thinking?)
The Nautilus can be harnessed or used in booster mode. That is an option if your child has outgrown his current seat but you still want him in a 5 point harness. The Britax Frontier is similar.
