You are correct, in 2014 VPG changed their name to Mobility Ventures and started to produce the MV-1 again.
The Curt Trailer Hitch Receiver - Custom Fit - Class III # C13122 you were looking at is confirmed to fit the 2011-2012 VPG MV-1 and 2014-2018 Mobility Ventures MV-1.
If you are planning on towing with your MV-1 you will also need a trailer wiring harness # C59236, and a ball mount, hitch ball, and hitch pin and clip which is all found in the etrailer Ball Mount Kit # 989900.
