Electricity? Never touch the stuff
I'm hiring an electrician to run a 50 amp line at my daughter's house for my RV. I only need 50amps because I have two A/C units. It's a 30' toy hauler. No W/D hookups. Everything is 110 (I believe). ...

OMG... I wish people would stop referring to "phases" in reference to 120/240 volt circuits and services. In the elec. industry, the two hot legs are always referred to as simply line 1 and line 2. See diagram below.
To the OP, (if he comes back) I would not ignore voltage drop in the circuit if wanting the full 50 amps available (as opposed to just needing to run converter, fridge and other light loads). That would include overall length of all wiring from RV panel all the way back to the panel in the house. A calc. should also consider actual voltage at the house's panel. It is possible that heavier ga. wire is needed, but probably okay.

The two hot legs are 120 degrees apart and referred to as phase A & B (or A & C or B & C) and the voltage from the neutral to a phase is 120 volts. See diagram below. Since it's uncommon for RVs to have 240 volt appliances, the reduced voltage of 208 doesn't affect anything. 120/208 volt services in CGs aren't very common but they are out there and you'd never know unless you used a voltmeter.
3 phase for residential and CG's??? Yea right that will happen right after the US switches from 120V to 240V. The UK did that right with 220V and 50Hz.
