Hmmm... I guess I might be able to survive something like this with a Nintendo Switch, some DC power, and carefully chosen snacks. If the vehicle has a thin folding bench seat in the back I would be out. Also you might want to have a lawyer draft rules for using the stereo or all three of you might be found dead somewhere enroute
Also I don't think I saw mentioned what time of year you're planning for this, is it soon? Running into snow along the way could throw any time projections out the window
