Okay. Something is definitely screwed up. Around forty years ago, three prong 240VAC plugs and outlets were common, with neutral and ground tied together ... or just neutral with no ground. (The latter is why people sometimes got shocks from old dryers and ranges.)
In all cases, missing ground prong is
always a serious problem.
Treeseeker is right, you need a manufactured adapter. Homebrews are often screwed up.
If you have a manufactured adapter, and the outlet you're plugging into is wired correctly, then the problem is inside your motorhome.
