Just a thought, but many older homes just have 100 amps available. If you put a 50/30/20 next to the driveway, your guests MH may cut you short, when using many household appliances at once.

Meh. The worst that happens is you pop the main breaker, reset it, educate everybody and move on. Many Electric Vehicle owners live in houses with 100 amp service. An EV can pull 32 amps at 240 volts. But the chargers are all programmable and they just charge at night. They learn fast after the main 100 amp breaker kicks on the house. Just have to do a little power management. Easy to do with an RV.
Though my house has been updated there are still older homes in my area that use Cartridge Fuses for the mains and screw in fuses or fusestats for the smaller circuits. So if you blow a main cartridge fuse it can be a struggle to find one on a late Sunday afternoon when all the stores are closed. (People should keep spares but, I have known people who didn't )
