Remember that road fatigue is cumulative; you'll be worn out by day three or four and would benefit greatly from a full day of not driving at all.
The other thing to remember is that Google Maps 'lies'. Their time estimates, 42-44 hours in your case, are based on always driving at the speed limit and assume no traffic and no stops whatsoever. "Your time may vary" is an understatement. It will vary and it will be noticeably longer than predicted. Also I personally would not take either of the two routes suggested by their algorithm. Their northern route, basically I-76/I-90/I-80 is heavily urbanized and sees a lot of trucking in it's eastern portion (Pittsburgh, Cleveland, Toledo, Chicago). That route also consists entirely of toll roads between Philly and Chicago. The southern route (I-76/I-70/I-44/I-40/I-5) would have you driving through the desert Southwest just as things are really starting to heat up. Days in the 80s or 90s are to be expected.
Instead I would split the difference and use I-76/I-81/I-68/I-79/I-64/I-70/I-29/I-80. That would still leave you some tolls (a potion of the PA Tpk), some cities (Louisville, St. Louis, Kansas City, Salt Lake City) and some heat in northern Nevada, but it's a good compromise and is roughly the same length as the two options Google comes up with.
But, again, the primary constraint in your plans is time. I would add a day to pick up, learn and load the RV at the start and to unload and return the vehicle at the end. I'd also, as noted, add another day off somewhere along the way, and finally a day at least for that "family adventure" aspect of the trip. So nine days total. I know it's tempting to want to do the trip in as little time as possible and as cheaply as possible, but you want it to be fun, not a slog through Hades.
Finally, once you decide what works for you, make motel, RV park and/or campsite reservations in advance. Not only will this insure that you'll find a place at the end of the day (June is a heavy vacation month) but will help keep you on schedule. Please let us know what route/timing you choose as we can then offer some attractions/adventures available to you as well as suggest some final tweaks.
