You're quite a bit off in terms of charging speeds off 120 and 240V. Even with a Model 3 (which is among the fastest charging EVs off AC power, due to its efficiency) you're closer to around ~3-4mi of range per hour (so, 16-24mi in 6 hours). It gets much much worse in cold climates, where 120V may not even charge the car at all (although, it will prevent charge loss). 120V, 20A outlets are much better (~7mi of range per hour), but still that's only 42mi/6 hrs. Assuming you have a full 240V 50A outlet (i.e., a NEMA 14-50), you're getting maybe 30 miles of range an hour. That's max 60mi/2 hours. Also, unless you have that outlet available for EV charging or an RV, it's most likely your home will only readily have a dryer outlet available for hookup (so, 22mi range per hour max) which is less current. Numbers get significantly worse (up to say, half the rates quoted above) depending on the vehicle used for charging. All that to say, it's still pretty livable in my experience. As long as you aren't exceeding ~100mi/day consistently you can just constantly charge over 120V/20A and get by just fine locally. For road trips, I'd consider 120V as a last resort until you can limp to a DC fast charger.
