You really don't want to use that 3 prong outlet for your RV. It is a 240v 50A outlet with no neutral. The 3 wires are 2 hots and a ground. For an RV you need a 4 wire connection with a separate neutral and ground.
There shouldn't be a ready made adapter.
It is possible to use the ground for the neutral and make it work but it's not advisable at all. It could pose a rather large safety hazard.
By the way, 50 amp RV outlets are not 50A 120v; they are 50A 240/120v split phase.
In my non electrician view that's the most informative post thus far and I would say what you have is a 50A 240V receptacle and as KD4UPL states will have to hots and a ground. What you want is a 50A 240/120 receptacle which is a standard range configuration which will have two hots, a ground and a neutral. The 50A 240V configuration does not have 120V available to it whereas the 50A 240/120V has both 240 and 120 V available to it. Typical 50A RV use the 50A 240/120V configuration.
As mentioned it's work checking to see if the line feeding that existing 50A/240V receptacle has an unconnected neutral which would allow an easy conversion to a 50A 240/120V configuration w/o running a lot of new wire.
