How big is the generator? Fuel use is proportional to size and output.
4 KW generator at half load will burn about three pounds of fuel per hour, at full load about 5 1/2 pounds per hour. You can scale that up for other generator sizes.
20 gallons of LPG is about 82 pounds, so 50 hours does not seem unreasonable for running one A/C, which needs about 2 KW when running, somewhat more to start.
In bulk, LPG sells for about the same price per BTU as the liquid fuels. It should look like less per gallon than gas, if it doesn't have road use taxes, but often when filling a tank on any kind of motor vehicle the LPG distributor will charge the taxed price.
So cost to run a RV generator shouldn't vary much by fuel type. LPG, however, will likely be the least convenient to refuel.
