3 prong 50 amp plug to 4 prong 50 amp ????

We lost a good camping friend last night to a sudden heart attack and will be going up to their place to help out with the family/wake/funeral. He has a 3 prong 50 amp outlet on side of garage which I assume is a std dryer type 220 outlet (can't check because we are not there yet). Is there an adapter to go from 3 prong 220V to the 4 prong outlet we use at campground? Just wondering if anyone has done this and if adapter is available. Will use the 30 amp outlet in his barn if this is not recommended (and would check any adapter set-up with my surge guard before plugging in coach anyway).

Thanks for advice.

Story short, don't mess with it.
Now if you'd like to fix it for a 30amp RV outlet, then replace the double pole breaker in the circuit box with a single pole 30amp, use one on the wires as a neutral and marking same with white tape. Now use a 30amp RV outlet and wire per instruction, so that you'll now have 120v across the hot and neutral legs and the ground that you should have previously had for the odd third leg. For a 50amp coach, use the standard converter cord available at Walmart or Camping World.
